You can do something like the following:
-) Define your two select lists, I'll leave that part out..But let's assume
they are named listA and listB. We'll also assume that a form exists named
form1.
-) In your page or component, define a method that looks somewhat like this:
@EventListener(targets = "listA", events = "onchange", submitForm="form1")
public void listASelected(IRequestCycle cycle)
{
cycle.getResponseBuilder().updateComponent("listB");
}

Hi,
I would like to find out how I can auto-update a drop down list in a
form when another drop down list changes. For example, in a HTML
form, I have two <select> elements. Let's say the first <select> has
a list of department names and upon selecting one, it updates the
second <select> with a list of employees for the selected department.
Also, the values of the two <select> elements are retrieved from a
database table.
What is the typical approach of dealing with this type of problem? Is
there any article that explains this? I would appreciate if anyone
who has dealt with a similar problem above provide me with some
suggestions or pointers. Thanks.
