Hi,

with group options, there is a problem with user UX/UI
when adding a new element the line with the new element does not appear in the drop-down menu below, and in order to add a new element, the user need to press enter instead of clicking on the new element to put the element in selected value
for unexperienced users this is a very non-trivial action

can you fix this?
may be add param onCreateDefaultGroup or other variant?
