| The `<iron-flex-layout>` component provides simple ways to use [CSS flexible box layout](https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Flexible_boxes), also known as flexbox. This component provides two different ways to use flexbox: | |
| 1. [Layout classes](https://github.com/PolymerElements/iron-flex-layout/tree/master/classes). The layout class stylesheet provides a simple set of class-based flexbox rules. Layout classes let you specify layout properties directly in markup. | |
| 2. [Custom CSS mixins](https://github.com/PolymerElements/iron-flex-layout/blob/master/iron-flex-layout.html). The mixin stylesheet includes custom CSS mixins that can be applied inside a CSS rule using the `@apply` function. | |
| A complete [guide](https://elements.polymer-project.org/guides/flex-layout) to `<iron-flex-layout>` is available. | |

| Material design: [Menus](https://www.google.com/design/spec/components/menus.html) | |
| `<paper-menu>` implements an accessible menu control with Material Design styling. The focused item | |
| is highlighted, and the selected item has bolded text. | |
| <paper-menu> | |
| <paper-item>Item 1</paper-item> | |
| <paper-item>Item 2</paper-item> | |

| ### Styling | |
| The following custom properties and mixins are available for styling: | |
| Custom property | Description | Default | |
| ----------------|-------------|---------- | |
| `--paper-menu-background-color` | Menu background color | `--primary-background-color` | |
| `--paper-menu-color` | Menu foreground color | `--primary-text-color` | |
| `--paper-menu-disabled-color` | Foreground color for a disabled item | `--disabled-text-color` | |
| `--paper-menu` | Mixin applied to the menu | `{}` | |
| `--paper-menu-selected-item` | Mixin applied to the selected item | `{}` | |
| `--paper-menu-focused-item` | Mixin applied to the focused item | `{}` | |
| `--paper-menu-focused-item-after` | Mixin applied to the ::after pseudo-element for the focused item | `{}` | |
| ### Accessibility | |
| `<paper-menu>` has `role="menu"` by default. A multi-select menu will also have | |
| `aria-multiselectable` set. It implements key bindings to navigate through the menu with the up and | |
| down arrow keys, esc to exit the menu, and enter to activate a menu item. Typing the first letter | |
| of a menu item will also focus it. | |

| `iron-meta` is a generic element you can use for sharing information across the DOM tree. | |
| It uses [monostate pattern](http://c2.com/cgi/wiki?MonostatePattern) such that any | |
| instance of iron-meta has access to the shared | |
| information. You can use `iron-meta` to share whatever you want (or create an extension | |
| [like x-meta] for enhancements). | |
| The `iron-meta` instances containing your actual data can be loaded in an import, | |
| or constructed in any way you see fit. The only requirement is that you create them | |
| before you try to access them. | |
| Examples: | |
| If I create an instance like this: | |
| <iron-meta key="info" value="foo/bar"></iron-meta> | |
| Note that value="foo/bar" is the metadata I've defined. I could define more | |
| attributes or use child nodes to define additional metadata. | |
| Now I can access that element (and it's metadata) from any iron-meta instance | |
| via the byKey method, e.g. | |
| meta.byKey('info').getAttribute('value'); | |
| Pure imperative form would be like: | |
| document.createElement('iron-meta').byKey('info').getAttribute('value'); | |
| Or, in a Polymer element, you can include a meta in your template: | |
| <iron-meta id="meta"></iron-meta> | |
| ... | |
| this.$.meta.byKey('info').getAttribute('value'); | |

| * `Use Polymer.IronValidatableBehavior` to implement an element that validates user input. | |
| * Use the related `Polymer.IronValidatorBehavior` to add custom validation logic to an iron-input. | |
| * | |
| * By default, an `<iron-form>` element validates its fields when the user presses the submit button. | |
| * To validate a form imperatively, call the form's `validate()` method, which in turn will | |
| * call `validate()` on all its children. By using `Polymer.IronValidatableBehavior`, your | |
| * custom element will get a public `validate()`, which | |
| * will return the validity of the element, and a corresponding `invalid` attribute, | |
| * which can be used for styling. | |
| * | |
| * To implement the custom validation logic of your element, you must override | |
| * the protected `_getValidity()` method of this behaviour, rather than `validate()`. | |
| * See [this](https://github.com/PolymerElements/iron-form/blob/master/demo/simple-element.html) | |

| `<iron-input>` adds two-way binding and custom validators using `Polymer.IronValidatorBehavior` | |
| to `<input>`. | |
| ### Two-way binding | |
| By default you can only get notified of changes to an `input`'s `value` due to user input: | |
| <input value="{{myValue::input}}"> | |
| `iron-input` adds the `bind-value` property that mirrors the `value` property, and can be used | |
| for two-way data binding. `bind-value` will notify if it is changed either by user input or by script. | |
| <input is="iron-input" bind-value="{{myValue}}"> | |
| ### Custom validators | |
| You can use custom validators that implement `Polymer.IronValidatorBehavior` with `<iron-input>`. | |
| <input is="iron-input" validator="my-custom-validator"> | |
| ### Stopping invalid input | |
| It may be desirable to only allow users to enter certain characters. You can use the | |
| `prevent-invalid-input` and `allowed-pattern` attributes together to accomplish this. This feature | |
| is separate from validation, and `allowed-pattern` does not affect how the input is validated. | |
| <!-- only allow characters that match [0-9] --> | |

| `<paper-input-container>` is a container for a `<label>`, an `<input is="iron-input">` or | |
| `<iron-autogrow-textarea>` and optional add-on elements such as an error message or character | |
| counter, used to implement Material Design text fields. | |
| For example: | |
| <paper-input-container> | |
| <label>Your name</label> | |
| <input is="iron-input"> | |
| </paper-input-container> | |
| ### Listening for input changes | |
| By default, it listens for changes on the `bind-value` attribute on its children nodes and perform | |
| tasks such as auto-validating and label styling when the `bind-value` changes. You can configure | |
| the attribute it listens to with the `attr-for-value` attribute. | |
| ### Using a custom input element | |
| You can use a custom input element in a `<paper-input-container>`, for example to implement a | |
| compound input field like a social security number input. The custom input element should have the | |
| `paper-input-input` class, have a `notify:true` value property and optionally implements | |
| `Polymer.IronValidatableBehavior` if it is validatable. | |
| <paper-input-container attr-for-value="ssn-value"> | |
| <label>Social security number</label> | |
| <ssn-input class="paper-input-input"></ssn-input> | |
| </paper-input-container> | |
| ### Validation | |
| If the `auto-validate` attribute is set, the input container will validate the input and update | |
| the container styling when the input value changes. | |
| ### Add-ons | |
| Add-ons are child elements of a `<paper-input-container>` with the `add-on` attribute and | |
| implements the `Polymer.PaperInputAddonBehavior` behavior. They are notified when the input value | |
| or validity changes, and may implement functionality such as error messages or character counters. | |
| They appear at the bottom of the input. | |
| ### Prefixes and suffixes | |
| These are child elements of a `<paper-input-container>` with the `prefix` | |
| or `suffix` attribute, and are displayed inline with the input, before or after. | |
| <paper-input-container> | |
| <div prefix>$</div> | |
| <label>Total</label> | |
| <input is="iron-input"> | |
| <paper-icon-button suffix icon="clear"></paper-icon-button> | |
| </paper-input-container> | |
| ### Styling | |
| The following custom properties and mixins are available for styling: | |
| Custom property | Description | Default | |
| ----------------|-------------|---------- | |
| `--paper-input-container-color` | Label and underline color when the input is not focused | `--secondary-text-color` | |
| `--paper-input-container-focus-color` | Label and underline color when the input is focused | `--primary-color` | |
| `--paper-input-container-invalid-color` | Label and underline color when the input is is invalid | `--error-color` | |
| `--paper-input-container-input-color` | Input foreground color | `--primary-text-color` | |
| `--paper-input-container` | Mixin applied to the container | `{}` | |
| `--paper-input-container-disabled` | Mixin applied to the container when it's disabled | `{}` | |
| `--paper-input-container-label` | Mixin applied to the label | `{}` | |
| `--paper-input-container-label-focus` | Mixin applied to the label when the input is focused | `{}` | |
| `--paper-input-container-label-floating` | Mixin applied to the label when floating | `{}` | |
| `--paper-input-container-input` | Mixin applied to the input | `{}` | |
| `--paper-input-container-underline` | Mixin applied to the underline | `{}` | |
| `--paper-input-container-underline-focus` | Mixin applied to the underline when the input is focused | `{}` | |
| `--paper-input-container-underline-disabled` | Mixin applied to the underline when the input is disabled | `{}` | |
| `--paper-input-prefix` | Mixin applied to the input prefix | `{}` | |
| `--paper-input-suffix` | Mixin applied to the input suffix | `{}` | |
| This element is `display:block` by default, but you can set the `inline` attribute to make it | |
| `display:inline-block`. | |

| Material design: [Text fields](https://www.google.com/design/spec/components/text-fields.html) | |
| `<paper-input>` is a single-line text field with Material Design styling. | |
| <paper-input label="Input label"></paper-input> | |
| It may include an optional error message or character counter. | |
| <paper-input error-message="Invalid input!" label="Input label"></paper-input> | |
| <paper-input char-counter label="Input label"></paper-input> | |
| It can also include custom prefix or suffix elements, which are displayed | |
| before or after the text input itself. In order for an element to be | |
| considered as a prefix, it must have the `prefix` attribute (and similarly | |
| for `suffix`). | |
| <paper-input label="total"> | |
| <div prefix>$</div> | |
| <paper-icon-button suffix icon="clear"></paper-icon-button> | |
| </paper-input> | |
| A `paper-input` can use the native `type=search` or `type=file` features. | |
| However, since we can't control the native styling of the input (search icon, | |
| file button, date placeholder, etc.), in these cases the label will be | |
| automatically floated. The `placeholder` attribute can still be used for | |
| additional informational text. | |
| <paper-input label="search!" type="search" | |
| placeholder="search for cats" autosave="test" results="5"> | |
| </paper-input> | |
| See `Polymer.PaperInputBehavior` for more API docs. | |
| ### Focus | |
| To focus a paper-input, you can call the native `focus()` method as long as the | |
| paper input has a tab index. | |
| ### Styling | |
| See `Polymer.PaperInputContainer` for a list of custom properties used to | |
| style this element. | |

| it will cancel whenever the user taps outside it or presses the escape key. This behavior is | |
| configurable with the `no-cancel-on-esc-key` and the `no-cancel-on-outside-click` properties. | |
| `close()` should be called explicitly by the implementer when the user interacts with a control | |
| in the overlay element. When the dialog is canceled, the overlay fires an 'iron-overlay-canceled' | |
| event. Call `preventDefault` on this event to prevent the overlay from closing. | |
| ### Positioning | |
| By default the element is sized and positioned to fit and centered inside the window. You can | |
| position and size it manually using CSS. See `Polymer.IronFitBehavior`. | |
| ### Backdrop | |
| Set the `with-backdrop` attribute to display a backdrop behind the overlay. The backdrop is | |
| appended to `<body>` and is of type `<iron-overlay-backdrop>`. See its doc page for styling | |
| options. | |
| ### Limitations | |
| The element is styled to appear on top of other content by setting its `z-index` property. You | |
| must ensure no element has a stacking context with a higher `z-index` than its parent stacking | |
| context. You should place this element as a child of `<body>` whenever possible. | |

| `<iron-dropdown>` is a generalized element that is useful when you have | |
| hidden content (`.dropdown-content`) that is revealed due to some change in | |
| state that should cause it to do so. | |
| Note that this is a low-level element intended to be used as part of other | |
| composite elements that cause dropdowns to be revealed. | |
| Examples of elements that might be implemented using an `iron-dropdown` | |
| include comboboxes, menubuttons, selects. The list goes on. | |
| The `<iron-dropdown>` element exposes attributes that allow the position | |
| of the `.dropdown-content` relative to the `.dropdown-trigger` to be | |
| configured. | |
| <iron-dropdown horizontal-align="right" vertical-align="top"> | |
| <div class="dropdown-content">Hello!</div> | |
| </iron-dropdown> | |
| In the above example, the `<div>` with class `.dropdown-content` will be | |
| hidden until the dropdown element has `opened` set to true, or when the `open` | |
| method is called on the element. | |

| Material design: [Dropdown buttons](https://www.google.com/design/spec/components/buttons.html#buttons-dropdown-buttons) | |
| `paper-menu-button` allows one to compose a designated "trigger" element with | |
| another element that represents "content", to create a dropdown menu that | |
| displays the "content" when the "trigger" is clicked. | |
| The child element with the class `dropdown-trigger` will be used as the | |
| "trigger" element. The child element with the class `dropdown-content` will be | |
| used as the "content" element. | |
| The `paper-menu-button` is sensitive to its content's `iron-select` events. If | |
| the "content" element triggers an `iron-select` event, the `paper-menu-button` | |
| will close automatically. | |
| Example: | |
| <paper-menu-button> | |
| <paper-icon-button icon="menu" class="dropdown-trigger"></paper-icon-button> | |
| <paper-menu class="dropdown-content"> | |
| <paper-item>Share</paper-item> | |
| <paper-item>Settings</paper-item> | |
| <paper-item>Help</paper-item> | |
| </paper-menu> | |
| </paper-menu-button> | |
| ### Styling | |
| The following custom properties and mixins are also available for styling: | |
| Custom property | Description | Default | |

| Material design: [Surface reaction](https://www.google.com/design/spec/animation/responsive-interaction.html#responsive-interaction-surface-reaction) | |
| `paper-ripple` provides a visual effect that other paper elements can | |
| use to simulate a rippling effect emanating from the point of contact. The | |
| effect can be visualized as a concentric circle with motion. | |
| Example: | |
| <div style="position:relative"> | |
| <paper-ripple></paper-ripple> | |
| </div> | |
| Note, it's important that the parent container of the ripple be relative position, otherwise | |
| the ripple will emanate outside of the desired container. | |
| `paper-ripple` listens to "mousedown" and "mouseup" events so it would display ripple | |
| effect when touches on it. You can also defeat the default behavior and | |
| manually route the down and up actions to the ripple element. Note that it is | |
| important if you call `downAction()` you will have to make sure to call | |
| `upAction()` so that `paper-ripple` would end the animation loop. | |
| Example: | |
| <paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple> | |
| ... | |
| downAction: function(e) { | |
| this.$.ripple.downAction({x: e.x, y: e.y}); | |
| }, | |
| upAction: function(e) { | |
| this.$.ripple.upAction(); | |
| } | |
| Styling ripple effect: | |
| Use CSS color property to style the ripple: | |
| paper-ripple { | |
| color: #4285f4; | |
| } | |
| Note that CSS color property is inherited so it is not required to set it on | |
| the `paper-ripple` element directly. | |
| By default, the ripple is centered on the point of contact. Apply the `recenters` | |
| attribute to have the ripple grow toward the center of its container. | |
| <paper-ripple recenters></paper-ripple> | |
| You can also center the ripple inside its container from the start. | |
| <paper-ripple center></paper-ripple> | |
| Apply `circle` class to make the rippling effect within a circle. | |
| <paper-ripple class="circle"></paper-ripple> | |

| The `iron-icon` element displays an icon. By default an icon renders as a 24px square. | |
| Example using src: | |
| <iron-icon src="star.png"></iron-icon> | |
| Example setting size to 32px x 32px: | |
| <iron-icon class="big" src="big_star.png"></iron-icon> | |
| <style is="custom-style"> | |
| .big { | |
| --iron-icon-height: 32px; | |
| --iron-icon-width: 32px; | |
| } | |
| </style> | |
| The iron elements include several sets of icons. | |
| To use the default set of icons, import `iron-icons.html` and use the `icon` attribute to specify an icon: | |
| <link rel="import" href="/components/iron-icons/iron-icons.html"> | |
| <iron-icon icon="menu"></iron-icon> | |
| To use a different built-in set of icons, import the specific `iron-icons/<iconset>-icons.html`, and | |
| specify the icon as `<iconset>:<icon>`. For example, to use a communication icon, you would | |
| use: | |
| <link rel="import" href="/components/iron-icons/communication-icons.html"> | |
| <iron-icon icon="communication:email"></iron-icon> | |
| You can also create custom icon sets of bitmap or SVG icons. | |
| Example of using an icon named `cherry` from a custom iconset with the ID `fruit`: | |
| <iron-icon icon="fruit:cherry"></iron-icon> | |
| See [iron-iconset](iron-iconset) and [iron-iconset-svg](iron-iconset-svg) for more information about | |
| how to create a custom iconset. | |
| See the [iron-icons demo](iron-icons?view=demo:demo/index.html) to see the icons available | |
| in the various iconsets. | |
| ### Styling | |
| The following custom properties are available for styling: | |
| Custom property | Description | Default | |
| ----------------|-------------|---------- | |
| `--iron-icon-width` | Width of the icon | `24px` | |
| `--iron-icon-height` | Height of the icon | `24px` | |
| `--iron-icon-fill-color` | Fill color of the svg icon | `currentcolor` | |
| `--iron-icon-stroke-color` | Stroke color of the svg icon | none | |

| /** | |
| * The `iron-iconset-svg` element allows users to define their own icon sets | |
| * that contain svg icons. The svg icon elements should be children of the | |
| * `iron-iconset-svg` element. Multiple icons should be given distinct id's. | |
| * | |
| * Using svg elements to create icons has a few advantages over traditional | |
| * bitmap graphics like jpg or png. Icons that use svg are vector based so | |
| * they are resolution independent and should look good on any device. They | |
| * are stylable via css. Icons can be themed, colorized, and even animated. | |
| * | |
| * Example: | |
| * | |
| * <iron-iconset-svg name="my-svg-icons" size="24"> | |
| * <svg> | |
| * <defs> | |
| * <g id="shape"> | |
| * <rect x="12" y="0" width="12" height="24" /> | |
| * <circle cx="12" cy="12" r="12" /> | |
| * </g> | |
| * </defs> | |
| * </svg> | |
| * </iron-iconset-svg> | |
| * | |
| * This will automatically register the icon set "my-svg-icons" to the iconset | |
| * database. To use these icons from within another element, make a | |
| * `iron-iconset` element and call the `byId` method | |
| * to retrieve a given iconset. To apply a particular icon inside an | |
| * element use the `applyIcon` method. For example: | |
| * | |
| * iconset.applyIcon(iconNode, 'car'); | |
| * | |
| * @element iron-iconset-svg | |
| * @demo demo/index.html | |
| * @implements {Polymer.Iconset} | |

| Material design: [Dropdown menus](https://www.google.com/design/spec/components/buttons.html#buttons-dropdown-buttons) | |
| `paper-dropdown-menu` is similar to a native browser select element. | |
| `paper-dropdown-menu` works with selectable content. The currently selected | |
| item is displayed in the control. If no item is selected, the `label` is | |
| displayed instead. | |
| The child element with the class `dropdown-content` will be used as the dropdown | |
| menu. It could be a `paper-menu` or element that triggers `iron-select` when | |
| selecting its children. | |
| Example: | |
| <paper-dropdown-menu label="Your favourite pastry"> | |
| <paper-menu class="dropdown-content"> | |
| <paper-item>Croissant</paper-item> | |
| <paper-item>Donut</paper-item> | |
| <paper-item>Financier</paper-item> | |
| <paper-item>Madeleine</paper-item> | |
| </paper-menu> | |
| </paper-dropdown-menu> | |
| This example renders a dropdown menu with 4 options. | |
| Similarly to using `iron-select`, `iron-deselect` events will cause the | |
| current selection of the `paper-dropdown-menu` to be cleared. | |
| ### Styling | |
| The following custom properties and mixins are also available for styling: | |
| Custom property | Description | Default | |
| ----------------|-------------|---------- | |
| `--paper-dropdown-menu` | A mixin that is applied to the element host | `{}` | |
| `--paper-dropdown-menu-disabled` | A mixin that is applied to the element host when disabled | `{}` | |
| `--paper-dropdown-menu-ripple` | A mixin that is applied to the internal ripple | `{}` | |
| `--paper-dropdown-menu-button` | A mixin that is applied to the internal menu button | `{}` | |
| `--paper-dropdown-menu-input` | A mixin that is applied to the internal paper input | `{}` | |
| `--paper-dropdown-menu-icon` | A mixin that is applied to the internal icon | `{}` | |
| You can also use any of the `paper-input-container` and `paper-menu-button` | |
| style mixins and custom properties to style the internal input and menu button | |
| respectively. | |
