Fox Form + Modals

hi, I'm using your joomla plugin to create forms and I have a question. If I create a form and want to display it in a modal window, how can I connect messages about whether the form is filled out correctly with the modal window. Now when I submit the form, the modal window always closes as well.

0:51 preview of the generated page (I can open the form through a modal window - great)
1:00 a.m. after sending an incomplete form, I get a warning message of an incomplete form but outside the modal window - THAT'S MY PROBLEM
1:10 I go back to sleep, open the modal window again and there is a form with a voice. This is how I would like it to be displayed after submitting the form.

Can you help me?
Well thank you.

Your contact form dont working.

There have been no answers here for several years and I don't think there will be any in the future either. Too bad, I hope Demis is doing well!

This is the answer I feared the most.
It looks like I can look for a new plugin for forms.
Any tips?

I switched to balbooa forms!
