This task requires the radiobutton task to be finished first.
This task is about implementing support for comboboxes in the dgml files. It should work as an alternative visual representation of radiobuttons.
This could either be done with a backwards-compatible approach (introducing a "combo" attribute which would specify the name of the associated combobox). Or a completely new syntax. Of course if it can be achieved without big hacks we would prefer the backwards-compatible approach.
