Gravity Forms check all function (jQuery)

gravityforms-checkbox-checkall.js

// Needed this for a client project, thanks! I improved upon it to make it more generic so you don't have to look up individual IDs on elements:

jQuery(document).ready(function(){
// Check all in Gravity Forms
jQuery('.checkall li:first-child input').click(function() {
jQuery(this).parent('li').parent('ul').find(':checkbox').attr('checked', this.checked);
});
});

// Just add a class "checkall" to your checkbox form item in Gravity Forms, it assumes the first item in the list will be the "All" option.

It should go in the footer.php file, just before the closing tag. Make sure you wrap this in <script> tags.

Thank you for sharing!
