There are few steps to follow to submit the simple form.

Write your HTML for form:

1. Add form entries CPT to save your form into it.
2. Add your code of form in main template.
3. Write ajax request for submit form in <script> tag as in given example. In bind we have to pass the event. In bind_selector we have to pass either form which is submitted or button's class. In route_ajax we have to pass the template name which is playing role as handler of the form.
4. Write second template as form handler. It will work for:
   • Saving the current form in given CPT.
   • Show the thank you message. In this we are using template tag to replace the content with thank you message by selector given in selector attribute of it.
   • Mail the information to Admin and user.
