The submit button does not work because another event seems to block the reload of page. Looking in the console, I see an xml http post request which I do not want. Can you help to find the js code that blocks the reload. Should I post the header.php or the page-contact-us.php? Contact form 7 is installed, do I have to drop the plugin?
I used contact form 7, but would like to change the required property of a field dynamically: if the checkbox is clicked, the address fields should change from non-required to required. This can be done with php, but I dont know how to change the php code of cf7
