PowerPack’s Modal Popup Box module has the capability to create custom content, image, video, form, template popup boxes with various trigger options – auto-load, on-click, and exit intent. 

Here we will discuss how to trigger Modal Box by URL:

• Head over to Modal Box Settings > Settings > Trigger > Trigger Method > Other

• Copy the CSS Class from the field and save the settings.
• Now append the CSS class to the existing URL. For example, https://www.abc.com/#modal-5e69c651da2dc
• Add the URL to any button or link and it should trigger the Modal Box.
