The [deps/opt/ace](https://github.com/joshfire/jsonform/tree/master/deps/opt/ace) folder contains a minimal set of files from ACE to render a JSON input field. Beware that the code of `ace.js` needs to be encapsulated in `(function(require,define,requirejs) {...})(undefined,undefined,undefined);` before it may be used within JSON Form.

 - The [JSON Schema Validator](https://github.com/garycourt/JSV) is used to detect and report validation errors upon form submission. The [deps/opt](https://github.com/joshfire/jsonform/tree/master/deps/opt) folder contains a "build" of the JSON Schema Validator for use in JSON Form.

 - [jQuery UI Sortable](http://jqueryui.com/demos/sortable/) v1.8.20 or above is required for drag-and-drop support within arrays and tabarrays. Note the plugin itself depends on jQuery IU Core, jQuery UI Mouse, and jQuery UI Widget.
 - [wysihtml5](http://jhollingworth.github.com/bootstrap-wysihtml5/) is required if the form uses ```wysihtml5``` textarea fields.
