Error msg doesn't show up with Bootstrap4

[Joey33]

With bootstrap4 when client validation fails the <div class="invalid-feedback">error msg contens</div> is still hidden. The problem is that input element is wrapped in <div class="iti iti--allow-dropdown"> parent. When moving the error msg div into the same common parent, it shows up. Then you only have to reposition <div class="iti__flag-container"> so that it stays intact when error shows up. That's how I temporarily solved it. Just to let others know in case they run into the same issue.

Can you provide usage code for this scenario? How to move error div inside plugin?
