I'm looking to add a button to a card that when clicked calls a PL/SQL procedure. The purpose is to mark a card as a 'favorite'. Probably simple stupid, but I haven't found an example. If would best if if wasn't JavaScript (because I'm not a JavaScript programmer), but if the example is very simple I might be able to follow it. As an alternative to a button I can use a text string that when clicked called a PL/SQL procedure.
