</div>

I have form and a collection\_select control. I would like to update  
form fields (text box) when I select an item from the collection\_select  
box.

It’s like selecting template from the collection\_select and the template  
automatically loads to text boxes.

Any help?

You will either have to use javascript or ajax for this. If you don’t  
know about them then start with google.
