Divi Builder offers the option to hide your chosen modules on specific devices. These devices and their respective sizes (viewport width) are as follows:
Desktop: 981px or bigger
Tablet: 980px and not smaller than 767px
Phone: 767px or less
Note: Modules that are hidden on a device will display at 50% opacity in the Visual Builder.
The Disable on option can be accessed in two ways.
Right-click on the module and then choose the Disable item in the drop-down list. You can toggle the devices icons to enable/disable the module visibility.
Open the module settings modal and go to the Advanced > Visibility. You can toggle the device checkbox to enable/disable the visibility.
Note: The option is available on all sections, rows and content modules, except for columns.
