I wanted to know how do I add a thank you message after submitting a form. I want the people to stay on the same page. I couldn't find a place for a message in the setting of the form.
In order to show a Thank You message on the same LP, you will need to add a script to the page. You can add an HTML element to the page or add the script right after the form in the HTML of the page.
Here is a link to the answer in detail and the code.
Please make sure to change something in the script: </strong. change to </strong>
