Hi Rick,
I’m glad the Validator is helping.
I haven’t looked at the details, but I have tried your code and it works. I added this line to my demo and I do see the popover:
self.validator.required(self.multi_select_drop_down_1,
events=['change'],
placement='left')
I noticed that with placement = 'right' on the demo, the popover is barely visible on the right of the form.
Perhaps the popover appears outside of the visible area?
The placement of the popovers can be a problem with narrow forms or forms embedded in an alert. And perhaps on mobile platform (I haven’t tried)
Let me know if that’s the problem and you can fix it by changing the side of the popover or if it really doesn’t work.
The Anvil Extra guys have already fixed a couple of problems I reported when I added the popover to the Validator. Now the positioning is a little better, but still not perfect.
