With MB Builder and MB Front End Submission (the bundled plugin) I have created a front-end form with some fields set as required.
The shortcode sets the form to be submitted via Ajax.
Unfortunately, the UI does not display validation messages about required fields but the success message instead.
The submission, however, is not being saved to the database (what is correct).
Can you confirm this issue? How can I display validation messages in Ajax front-end submission?
