How to make RadicalFORM and Bootstrap 4 friends?

Question

Joomla

Good afternoon,
Please tell me, in the settings of the plugin in the AC there are fields:

• Javascript code #2 (for displaying a message)
  
• CSS class for invalid fields
  
• CSS class file errors
  

What to enter there to make friends with bootstrap 4?
I especially don’t understand how to display a message about successful sending in the modal window, googled, googled and not googled :(

Answer 1

Here are examples of ready-made forms on the developer's website https://hika.su/rasshireniya/radical-form/katalog-...
And the actual documentation https://hika.su/rasshireniya/radical-form
Documentation Bootstrap 4 Validation Form https:/ /getbootstrap.com/docs/4.5/components/forms...
After the Bootstrap documentation, it becomes clear that you can use native browser validation, or you can use bootstrap. Then the classes will be is-valid and is-invalid
