Hello,
I've been working to create a custom address control that the field looks like you would expect on an envelope window and when you click on the field it pops out the individual fields to edit.
When I test the control in the designer it looks correct

But when I build the solution, install it into CRM, add a text field and then add the custom control to the field I end up with this:

All of the fields stack.
The 'full address' string is built up
let multiLineAddress =
this.state.street1+"\n"
+this.state.street2+"\n"
+this.state.street3+"\n"
+this.state.city+" "
+this.state.state+" "
+this.state.zip
Does anyone have any idea what might be causing this?
