The Grid Block allows you to build advanced columns in your content. It uses flexbox, and even allows you to wrap the columns on multiple lines, meaning you can keep adding columns forever to build multi-line grids.
When you add a Grid Block, the Container Block is automatically inserted as the grid column. This gives you all of the power behind our Container Block directly inside your Grid.
Duplicate Grid Item
When a Container block is inside of a Grid block, you can use the Duplicate Grid Item option to duplicate the selected Container to the Grid.
