Dropdown "Required" not working

I have a dropdown that is required and the little star near the input name is visible in the browser and goes away when the user selects something in the dropdown, however, this behavior does not transfer to the app for some reason. In the app, the star is never visible. Another issue is that even in the browser AND in the app the user can move on to the next page without selecting anything.

What am I doing wrong?

Hi @tperry ,

How do you make the drop down "required"?

Is it a required field in the data source or have you coded something in the submit form logic?

It is only a required field in the app, I do not yet have anything making it required in the data source. 
All the other required fields work, but this one. 

Hi @tperry ,

A bit strange, but not an issue - you can control this on the submit form - something like (I will use MyField1, MyStar1 and a Variable vError). So on the Save button

      MyField1.Selected.Value   //last bit may be different depending on the source of the data

Also include UpdateContext({vError:false}) on screen exit and/or entrance.

The Visible property of the MyStar1 would be vError.
