Scrollbox or dropdown list navigation with mouse wheel?

Is there a way to allow users to navigate up/down a dropdown list or scrollbox with a vertical handle using the mouse wheel, please?

Hi @tkg_tim - we don’t have built-in mouse wheel support for the scroll box component at this time. This is something we can consider adding in the future, however!

The input system does listen for mouse wheel events. See the InputDeviceMouse::Movement::Z member in this file:

It would be possible to create a custom component (in C++) that listens for scroll wheel events and communicates with a scroll box component to change the offset accordingly by calling the SetScrollOffset method of the UiScrollBoxBus:

Thank you for your feedback. Let us know if there’s anything else we can help with!
