Here’s an example of how you might use Mai Display Taxonomy.
Create a Display term called “Home Handpicked”
Select some posts and add them to Home Favorites term via the post edit screen or by bulk edit. In a section of your homepage, add a Mai Post Grid block and in the “Entries” tab, get entries by Taxonomy and configure it to use the Display taxonomy with posts in the Home Handpicked category. Display taxonomy terms will never display on the front end, they are only for back-end organization.
