Adding and Removing Tags
Tags are essentially metadata keyword values that you can add to your topic (or assignment) to help you organize and find your data. When working in the Planner Explorer, you can select Tags from the Display Options menu to display this column of data. You can also search for topics or assignments by entering the name of a tag in the search field of either the Planner sidebar or Explorer.
You might have already added one or more tags during the topic creation process. The following processes describe how to create additional tags, or delete existing tags.
To add a new tag:
1. 
Click on the Add button under the Tags area of the topic or assignment.
2. Enter a tag name in the text field that appears to the left of the Add button.
As you type, a menu appears below the tag name. If your text matches an existing tag, the menu displays a list of options that you can select. If you are creating a new tag, the menu informs you that this is a New Value (as illustrated below).
You can press the Tab key or click the Add (+) button to enter additional tags.
3. Either Press Enter (Windows) or Return (macOS) on the keyboard, or click in a different area of the user interface to save the tag.
To remove a tag:
Click the X button to the right of the tag name.
The tag is removed from the topic (or assignment). If this is the only area where the tag exists, the tag is deleted from the Collaborate app. If the tag is associated with a different topic or assignment, it is saved as a known value and appears as a suggestion as you enter new tags.
