Input fields in Tree UI Element possible?

Hello *,

is it possible to have input fields (text fields or combo boxes) together with a label as leaves of a tree?

The tree structure must be set up dynamically. That seems to be possible. If input fields are allowed in the tree, how can I set them up at runtime (i.e. label, type, value, list content for a combo box)?

Any help appreciated!

Regards

Martin
