With the Data Source section you set the exact items that will be displaying in this particular grid.
Type of Grid can be a "Grid of Posts, Pages or Custom Post Types", which is the default. Choose this when you want to display individual posts in a grid. For example, a grid of all of the blog posts on your website. Or a grid of all of the images on your website. "Grid of Category or Taxonomy Terms" is the other option and is used to display the categories itself as grid items.
Use Post Types to pick the exact post types you want to display in the grid. These can be the standard "Posts" or "Pages" but also "Attachments" for images on your website or any other custom post type you might have. Choosing multiple post types is possible as well!

- Menu Order (for pages only)
- Custom Field (see below)
For a grid of terms you have the following options:
- Post Count
