Note that you concerns are mostly UI related and that is really the last concern here (and possibly apart from keeping popup open they are questionable as defaults, ListBox also doesn't have check boxes).
Making the controls inherit from MultiSelector
is a good start. There will be enough virtualization issues to tackle.
ListBox
hasSelectionMode
property, which can be set toMultiple
orExtended
.ComboBox
shared theCanSelectMultiple
property, which is set tofalse
initially. Setting it totrue
would require:It might make sense to make ComboBox inherit
MultiSelector
.I could also implement the feature, if I get some guidance (e.g. on which branch to implement).
