How You Can Filter Tasks Within Your Board using Labels
Filter by Labels
At the top right corner of your Board, you can see a Filter by labels button. Using this option, only the Tasks that match the labels you have set will be displayed on your columns.
To choose from the labels, click on the icon and select the specific ones you want the Tasks to be filtered by, so only the Tasks labeled with them will be revealed.
Once ready, you'll only see the Tasks in your Board that have the labels you've chosen in the search.
If you want to remove the bale filtering. Click on the label pictogram again, and deselect the ones you've previously chosen.
