I get it deployed and installed by forge and saw that spin button but there is no wheel shown and no animation was seen. It seems that the SVG markdown is not supported!?
Where we can see that the app requests the content of the page and then adds each row from the table as a wheel segment.
If there is no table on the page or no rows in the table, then there will be no segments to populate the wheel of fortune and therefore it will just show the black triangle:
Wow, you got it. Very hard to figure it out without reading the source. May I ask if there is anything I could resize the wheel panel in the edit mode, it is page-wide and too big. How could I make it resizable (with mouse)?
Only the last option will make the frame use the entire width of the page, while the first two will make the macro frame as well as the wheel itself smaller.
What happens when you click on the first two options, can you maybe share a screenshot?
