Adding Field to Mgr Form

I have this working, but I have an issue and a question:

The issue is that the input field is misaligned to the left on any form (the label is fine). It’s probably an outdated CSS specifier on the example page, but I can’t figure out which one or what it should be: http://svn.modxcms.com/docs/display/revolution20/Adding+Custom+Fields+to+Manager+Forms. For future reference, is there a tpl for the form items I could look at?

The question is: Is there an easy way to make the input accept a drag-and-drop from the Resource tree? I want to fill it with a resource ID.

Found the fix and updated the docs.

Still have two questions, though:

1. Editing the added form field doesn’t trigger "dirty" status.

2. Any easy way to implement drag and drop from the tree to get the ID in the input field?
