Tether is a great library for positioning stuff (tooltips, modals, hints, etc) in your web app.

But, as I use React, it was pretty problematic for me, as Tether mutates the DOM and React breaks miserably when it sees mutated DOM. The solution is to have the tethered element outside the part of the DOM tree which is controlled by React (in this case, I use document.body).

That's why I created 2 helpers to use Tether with React.

The first one, TetheredElement is a plain JS helper to create a new element, attach it to some other one via Tether, and populate it with some React component.

The second one, TetherTarget is a React component and it uses TetheredElement to integrate it further with React, so that you can attach components to each other with Tether, without leaving the cozy React/JSX world and worrying about manual DOM operations. Just write:

Tether Drop + React Portal + Redux

This is an example of using Tether Drop with React Portal (and Redux for managing the state). I was asked if using React Portal is redundant, as both libraries pull the content into the <body>. Using only Drop would cause an invariant violation in React becuase of the DOM mutation, so I'm using React Portal to first bring it outside without React complaining (I don't know how React Portal does it, I haven't checked out the source, but it works). Once it's out of React's supervision, I can apply Drop to it.

Dropdown.jsx is the actual dropdown component
App.jsx is just an demo that uses it

This is my lazy way out of this limitation using an existing library that has much more features than you need, but chances are that you're going to need a library like React Portal anyway for stuff like modals.

Notes

GitHub Markdown Theme for Visual Studio Code

This CSS stylesheet allows you to preview markdown files in VSCode using GitHub's mardown theme. This CSS was taken directly from the official GitHub Markdown repo. I replaced their top-level .markdown-body class with the body tag so it would work in VSCode, and added styling for the html tag to match GitHub's fixed-width container.

Instructions

Copy the CSS file to your computer
Copy the github-markdown.css file below to your computer. You can put it anywhere you want, but I chose to put it in the same folder as my VSCode settings file.
Edit your VSCode settings
If you want to use this theme for all of your projects, then edit your User Settings file. If you just want to use this them
