In Page Media Slider Layout
Category: Sections - Sections - Waterlogic Gallery and Sliders.
Content Blocks Documentation: https://docs.modmore.com/en/ContentBlocks/v1.x/Layouts.html
This layout should act only as a "Container" for the In Page Media Slider Items:
Adding these layouts will inherit the default settings for these as defined if they were to be used by themselves and will need to be adjusted accordingly (padding and margin mainly).
A pre-configured template for this has already been set up for this under Templates -> Sections - Waterlogic Gallery and Sliders -> In Page Slider. Documentation Can be found here.
