Organise your notes with tags on iCloud.com
You can use tags as a fast and flexible way to categorise and organise your notes. You can add one or more tags to a note, such as #shopping and #work, and easily filter your notes across folders using the Tag Browser.
Add tags to notes
You can type a tag anywhere in a note. Tags must be a single word, but you can use hyphens and underscores (for example, #meeting-minutes or #important_documents).
Go to icloud.com/notes, then sign in to your Apple Account (if necessary).
Select a note.
Type the number sign (#), then type a word — for example, #meeting or #important — or choose from the list of suggested tags. (Suggested tags appear if you have already added tags in Notes.)
Tags you add appear in the Tag Browser in the sidebar.
If you add a tag to a shared note, it appears as dimmed text to other participants who do not have the tag in their Tag Browser.
View notes with tags
Go to icloud.com/notes, then sign in to your Apple Account (if necessary).
Do one of the following:
To see a list of notes that contain a tag, click the tag in the Tag Browser in the sidebar.
To see a list of notes that contain multiple tags, click all of those tags in the sidebar.
