Can anyone help part of a form I am using will use 2 drop down menus, the first looks like this (just removed a few option value lines for this example)


<select name="area" id="area">
  <option value="en">England</option>
  <option value="cy">Wales</option>
  <option value="sc">Scotland</option>
</select>

How do I code the second dropdown menu to that only relevant options are available.

For example if England is selected it won't list places in Wales or Scotland.

There's a couple of ways to do it depending upon if you want to make a trip back to the server or download all possible data combinations up front.

A google for "cascading selects" will turn up a few methods for doing it either way.
