Hi all! Hi have another problem and I would to read your ideas! I have to dbtables: Categories and SubCategories (depending from Categories). I would like to let the user choose in a combo-box the category (this is simple) and then the sub-category in another combo-box containing only the subcategories of the selected category. With ASP I am used to download all the subcategories via an SQL at the page load and save the values in arrays. Then depending of the selected category load via Jscript the subcategories values dinamically. How can I do it in zope? Do I have to use the same way using JScript? Is there any other way not using the combo box? Thank you very much for your help but I need your help to use this wonderful environment as Zope is!
