// 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.
