options_list filtering by permissions
How would I go about filtering an options_list by permissions?
I've followed the simple modules tutorial and would like to modify it so that certain users can only select categories that are assigned to them. (i.e. A user in the finance dept. can only select the 'finance' category)
I've set up a categories_to_authors_model but I can't figure out how to filter the multi-select list in the article module so that it only shows the categories assigned to the selected author.
I would also like to do the same kind of filtering with the authors drop-down select menu....so a users can only select authors that they are allowed to.
Am I taking the wrong approach?
