How to remove the border from form fields?

how do you delete sections from a template form?

Hello theblackheartgroup,

I am not sure if I have understood your question correctly. Do you want to remove the white lined which is being disabled after the form fields? Please check the screenshot below:

Have you cloned this form from templates? You see the white lines because of the several custom css code injected in form.

To remove these lines from your form, please inject the following custom css code in your form:

.form-line {

  border: none !important;

}

The following guide should help you inject custom css code in form:  https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes 

Hope this helps.

Do get back to us if you have any questions.

Thank you!
