There is no special adapter for folder. It is a triplet-adapter for (form, request, context). The context just happens to be a folder. But the default IWidgets adapter is registered for (IFieldsForm, IFormLayer, Interface), which effectively means that any context will work. > However, I think the interface is fine and I don't think you need a > datamanager in your case.

I'll note that APIDOC is your friend. 1. I just started up Zope 3, where z3c.form* is installed. 2. Start APIDOC: http://localhost:8080/++apidoc++ 3. Click on the "Interfaces" module 4. Search for "IWidgets" 5. Click on "z3c.form.interfaces.IWidgets" 6. Go to the section "Adapters that provide this interface:" There you see one entry that tells you how the adapter is registered. You then basically have to make sure that your objects provide the necessary interfaces.
