How to Make Your Form Pop Up on Click
There are a few steps that you will need to take to make it pop up with the button click.
First, you have to make sure that you have your form mode set as Popup or All.
Next, you will need to add the pixel script to your site. Here is some documentation on how to do that: https://help.getleadforms.com/article/108-how-to-add-a-leadform-to-your-site
Then, you will need to set your target URL for the site that you would like to add it to.
After you've completed those steps, you will go to "Trigger with Button Click" and copy the class that I've highlighted in blue in the screen shot below and add it to the button. Also, make sure the URL of the button is a #.
