[jQuery] Jquery UI Doc?

[jQuery] Jquery UI Doc?


Hi, till now for my draggable and droppable effects I used Interface
plugin. Now I want to take a look at jquery ui, but I'm wondering if
exists a documentation better than the one on docs.jquery.com. For
example:
draggable( options )     Returns: jQuery
Creates new draggables on the nodeset supplied by the query.
Where I can find info about the options ?
If a doc doesn't exist, where I have to look inside the code?
Thank you.
