How to Create a Lightbox Form

March 26, 2024

A lightbox form is a window that pops up when visitors click on a link. It’s an easy way to share your forms with visitors. When the lightbox opens, it will overlay the page containing the link. The lightbox will look like this:

Customizing the Lightbox

If you want to customize the look and feel of the lightbox, click the Customize button as shown in the above screenshot. In the customization section, you have options to change the lightbox title, form dimensions, styles, colors, and an option to open on page load or not.

Customizing the Call-To-Action to Use an Image

If you want to use an image instead of a button/link to trigger the lightbox to open, you have to replace the following line:

<a class="btn lightbox-{formID}" style="margin-top: 16px">

…with the following:

<img src="{imageURL}" class="btn lightbox-{formID}">

You need to replace {formID} with your actual Form ID. It is the string of numbers at the end of the form URL. The same thing for the {imageURL}, you should also change it with the actual image URL. Please note that the class attribute’s value is very important for the lightbox to work when your visitor clicks the image.
