I’ve tried two different methods.
With ui_infield method 1, the interface leaves more of a space between each option on Windows. Even if I increase the size of the field to accommodate the scroll bar etc. it doesn’t display well. On Mac, it looks fine.
With ui_infield method 6, I have created a separate ui_infield command for each option. On windows it displays nicely, but on Mac it doesn’t show which is selected.
Method 1 images are attached…
