Excuse me for this history :) But long ago the MSN site was a good example. They used many IFRAMES for each dropdown. As a result on slow connections or unstable connection the MSN site was a bit problematic. Also this involved MS in implementing a lot of cross-frame scripting. Thus a wrong choice may cause need of more and more code.
My own opinion is frames but limit them carefuly to a number as low as possible. If you want you can reload the entire page to synch the listboxes avoid the frames, but this depends on the complexity of the queries. If you are able to simplify the page code to a point where the reload will not cause too much server overhead this will be the best solution. Why? No frames means you will deal with one form and you will avoid the efforts required to collect information from all the frames in order to submit a form in one of them. But if it is impossible to simplify the code - better put each listbox in seprate frame and submit the forms containing the boxes to the next frame in the chain.

When the parent dropdown is changed, vb/j script can repopulate The other dropdowns by changing the name/value fields in the object You may need to open a childe window to search the database though. > Jim Hundley > Development > www.vbti.com > --- Andy Hayman Kensington Computers Internet & Computers Systems Consultant Web <http://www.ken.co.uk> Email <mailto:[EMAIL PROTECTED]> Telephone 020 7835 1282 Fax: 020 7373 6900 Disclaimer This e-mail is confidential and intended solely for the use of the individual to whom it is addressed.
