You can enable or disable the “LightBox” of the Image Gallery Block using the Post Grid Combo plugin. This article will help you to enable or disable the Lightbox.
To get started, add the “Image Gallery” block.
Next, select a variation. For instance, I chose the “Layout-2” variation.
Now add your image from the media library or by any image source URL.
Now go to the Image Gallery Block and click on the Lightbox Tab.
Now you can choose between Enable Lightbox option, True or False. Here True means enabled the Lightbox, and false means disabled the Lightbox.
