I have a node reference field (User groups) in my content type; i would like to apply a filter on that field to show only the Groups belonged to the current user. How can i apply that filter in the content type insert/edit form?
I've written step by step instructions on how to do that.
Your setup will be a bit different since you don't use flags. "Step 3" describes how to use the "views reference" feature to show the referenced nodes on your node/add,edit page using views.
