How would I go about implementing something like this in on an admin page? I basically want to make a drag-and-drop sortable list on an admin page so that users can have the option of reordering, adding to, or deleting from a list of items specific to their account.
I guess my main questions are:
-For admin pages, how do I initialize jQuery, or is it already initialized?
-How do I link a .js file into the header of an admin page so that I can link my jQuery script?
-Is there anything else I need to know?
