I'd like to use the uicontrol of matlab and its arguments rather than the uidropdown. But I want the uidropdown functionality of having a popup menu of items that can be programmatically populated, but also the flexibility of allowing the user to define their own input value as well as the convenience of selecting from a list of values. Can this be done?

Only if you use a uicontrol style 'edit' together with the uicontrol style listbox . The primary value would be held in the edit uicontrol; the callbacks for the listbox would set the content of the edit uicontrol String property.

The Property Inspector provides an interface for editing the list box String property, but it is not exactly convenient.

Just ran across this link while searching the same thing... there appears to be an editable property. I havent tried it yet but it looks like what you want:
