The includes a commit from Drew. Have you based the branch on the master branch?

[Jacalz]

Also, please always fill out the checklist in the template and try to add some tests.

I think the tests won't run because of the same (re)base issue showing the stray commit.
Can you please try cherry picking your commit onto latest develop then force pushing to this branch again @williambrode? Hopefully that would resolve everything.

[Jacalz]

This seems to be working now. Can you please add a test for it?

I ran the test on develop without my changes and confirmed it fails.

[williambrode]

Mobile test failed - I can either change the test or change the code. Does someone know why the code doesn't focus the list for mobile? I was trying to change as little as possible but figured it might be worth asking.

li.onTapped = func() {
		if !fyne.CurrentDevice().IsMobile() {
			canvas := fyne.CurrentApp().Driver().CanvasForObject(l.list)
			if canvas != nil {
				canvas.Focus(l.list)
			}

			l.list.currentFocus = id
		}

		l.list.Select(id)
