Little Help - Spin Wheel And Get Results

I am new to UE4 - Looking for a starting point.

I looked over some of the example on Market Place, could not find an example.

Anyways, Here is what I am trying to accomplish.

I want the wheel to spin and select random categories. (swipe or click button to spin).

I attached an example:

In the example after spin, Cat 3 should be selected.
