Dynamic Dropdown
I have a question. I'm creating an insert record page. This page contains some form elements and one of them is a dynamic dropdown. Lets say generated from table users. Now what i dont know how to accomplish is ... When the user i want to select is not in this dropdown i want to add a new user in a new tab or light window and after i add it and close this lightwindow i want to see this user in my drowdown (without refreshing the page). So what i want is to generate (update) this dropdown each time i click on it to select a user...
Thanks
