Generation of dynamic input elements

Hi, I wonder if it is possible to create a form with dynamic input elements. In more details, imagine that I have a huge document repository. Documents are being inserted into that repository and they are separated by catalogs, profiles and properties. User must select catalog, then choose appropriate profile and then fill out all properties defined by selected profile in order to insert document into the repository. Some properties must be shown as dropdown menus, some as date fields and others as plain input text fields. So, is it possible to create this?

Thanks,

Sergei Emelinanov
