jQuery plugin to add common checkable menu items checkbox and radio and more features to jQuery.contextMenu. A very useful jQuery plugin jQuery.contextMenu supports text, textarea, checkbox, radio, etc., as item.type. Those allow you to embed form elements in the menu. Those may be useful in special cases, aside from whether users welcome a form that appears via right-click or not. But two types checkbox and radio are very popular UI many apps need, and behavior of those differs from that of common menu UI many apps have because those are embedded form elements. For example, those get a focus and tab-stop, a user can't make the focus move through to other menu items by pressing arrow keys. And also, those don't keep own state by itself, the states are cleared when the menu is reopened.
