WA Dynamic Dropdowns gives you complete control over nested, data-driven dropdown lists. The behaviors in this suite populate the "Child" list from the selection in the "Parent" list as well as provide list controls implemented on form buttons. In this example, there are two Recordsets on the page one each for the Parent and Child dropdown lists. Making a selection (or multiple selections) in the Parent list triggers custom code that dynamically populates the child list without page resubmission thus saving on server processing bandwidth.

The rest of the WA Dynamic Dropdowns suite gives you the ability to select your favorite automobiles from the Child list into a third called the "Select" dropdown list where you can then prioritize your selections by moving them up and down. You can remove individual entries from the Select List or select them all excluding the top or bottom option in the list, as these are not valid car selections. As you can see, all of the functionality is achieved client-side with no page reloads so your server gets hit only once the first time this page is loaded.
