Using from the CDN and it seems to work fine, except I'm getting this in console:

Uncaught TypeError: c.draggable is not a function

The readme says:

If true widgets are not movable/resizable. You don't even need jQueryUI
draggable/resizable.

I have a widget layout editor and I'm now trying to generate the static non-editable representation of it and would like to keep the requires to the minimum.
