Answer 1

I believe what you need is a popup window where you can have list of options, whenever your button is clicked show this window, hide it when user selects an item in the list or clicks outside of the working area. There is an example you can use as a reference:

You want a QComboBox:

The QComboBox widget is a combined button and popup list.
