I have displayed some contents from a default listings page to the combobox in another page.same page has another combo box which when selected should display its contents as appended to the old data in combo box..how can i do that?

Using ajax to clear the old content and replace the new content

[yeahuh]

I'm not sure the policy on links here but i have seen a decent example of doing just that using ajax at this site. http://www.dhtmlgoodies.com/scripts/...ed-select.html

I used it my self to build a dynamic car make / model select.

If linking is not allowed here and it gets removed just PM me and I'll send ya the info.
