2 buttons on 1 form, trying to do same action

Using Springboot, Java, Thymeleaf.
Have a form with a submit button that sends the form via email, and an earlier button on the form that adds a new section of form if button is clicked. Right now, when either button is clicked it is submitting the form and sending email.
How can I get the newSection button to do something separate?

This is happening because in your frontend you must have changed the action of the form to the new url, or you may just have changed the controller.

What I would suggest is to use JavaScript to disable default action in you new section button and then call the desired url manually through the JavaScript.

Comment if you have some doubt.
