Combo Box - Prevent Change with mouse wheel

[nikosliapis]

Hello,

I have a combo box and when the mouse hovers on it and I scroll the mouse wheel, the combo box scrolls and change data. I want to prevent that from happening and change the data on the combo box, only by mouse clicking. Is it possible?

Thank you.

Good catch!

I have learned new info.

By default, the F4 key opens or closes the list and the DOWN ARROW changes the current selection. In the extended UI, the F4 key is disabled and the DOWN ARROW key opens the drop-down list. The mouse wheel, which normally scrolls through the items in the list, has no effect when the extended UI is set.
