How to populate following instances of dhtmlxcombo element

I have three combo boxes and need to populate options data, from XML files, into the next combo box, based on the selection of the first combo box.

For example: I select Manufacturer in the first combo box, then all Models made by the selected manufacturer will/should be populated in the second combo box and on selecting the model, all Tertiary options will/should be populated in the third combo box.

Any ideas on how to do this with dhtmlxcombo? :confused:

Thanks in advance!

See this sample with your situation:

Thanks! that looks like it will do the trick :smiley:

Just need to figure how to make the combos stay there permanantly.

This way can recommend you using onCHange event handler. See attached sample
