dynamically dependent list boxes

madhuri.t · #1 Apr 28th, 2006, 13:45

I want to create two dynamically dependent list boxes. The first one being the main which retrieves the data from the database and second one being the child. When a value in the first list box is clicked, the second one should get populated. I am not too comfortable with Arrays, is it possible to workout the solution in some other way. If possible please point me to some useful sites. Thanks in advance.

There are several ways to work around this, and the ruth is... it's up to you how you do it.

Method 1
Start form by showing list A.
Don't show list B because you do't yet have a value for it.
Submit the form whenever value in list A changes.
USe the submitted value of A to populate list B.

Method 2
Use CSS. I can explain this if you don't get how to use the method above.
It saves having to reload the page but it's more complicated - and you need to understand some basic CSS.

Or you can ignore what I said and read this:
