The on_change vs on_select difference
The difference between on_change and on_select is:
on_changewill be called when the state changes, either with a click or space/enter keypress confirmation.on_selectdiffers most when the user is navigating by keyboard. Once the user is pressing e.g. the arrow keys, the selection is changing, but not the state.
