I'm working on service request form that has items that are shown upon selection of an option selected from a drop down menu. When an option is selected from the drop down menu, another drop down menu is shown and when an option is selected from the second drop down menu, a check box is now visible. The problem is that when a different option is selected from the first drop down menu, the checkbox is still visible.
Hopefully there is an expression that deals with that quite nicely.
I hope that makes sense, thanks in advance
