The enclosed dictionary is even overkill, but it's flexible enough for example if someone wants to provide other attributes like css or whatever. Assuming you pass directly the entire string attribute-value.

That last one would break existing code.
Patches welcome! :-)

When the group changes, the component starts a new group. If the "label" binding is present, it is used to separate groups, otherwise a blank option is used. There is not much to it, you just have to return a different value for group when appropriate for the data bound to the list.
