Then add this code to the form post submit field:

In the code, replace page_url with the page URL you want to open.

For example: <a href="#lightbox_thank-you" data-delay="1" class="js-post-submit-lightbox" hidden></a>

You can also abjust a delay before the lightbox opens. By default the delay is set to 1 second. To change it, edit the data-delay attribute. For example, to set a delay to 2 seconds, replace data-delay="1" with data-delay="2" in the code: <a href="#lightbox_thank-you" data-delay="2" class="js-post-submit-lightbox" hidden></a>
