1. Category Filters (for Post-Based Grids)
Assign categories to your posts that you would like to filter.
Next, select those categories as your Grid's main source.
And then from the grid's "Nav-Filter-Sort" tab, add the "Filter" control to one of the grid's navigation dropzones.
Next, scroll to the "Filter Groups" section, and select the categories you wish to use for the Filters.

2. Category Filters for Custom Grids
Select "Edit Element" to add categories to your custom grid items.
Next, scroll to "Other -> Filter", and enter the "categories" you wish to assign to the item.
Quick Tip #1

Quick Tip #2
Assign multiple "categories" to an item by separating them with commas as shown in this screenshot.
Next, from the grid's "Nav-Filter-Sort" tab, add the "Filter" control to one of the grid's navigation dropzones.
