Remove Custom Form Code

How do I remove all custom form code and just use basic bootstrap code/validation?

I've tried using <div class="form-widget customjs"> but it doesn't validate required fields (basic Bootstrap). Or, removing that div all together.

In the functions.min.js, I have commented out the AjaxForm Functions.

I figured it out. Please close this ticket. Thank you.
