Tags are a great way for you to keep your collections organized however you'd like! You can tag different photoshoot types, locations, or even your personal preferences.
To add a tag to a Collection, hover over the Collection thumbnail and then click on the drop down menu arrow that should appear in the top right corner. Next, click "Edit".
Feel free to add as many tags as you'd like under "Tags", separating each one with a comma, and then click "Update".
You can now see those tags at the top of your application, and can click on them to pull up any Collection related to those tags. You can even apply more than one tag to narrow down your selection even more!
