References are a part of our Relationships feature — making it easy to find tasks and Docs that would usually get lost in the cracks.
When you mention a task or Doc using the @mention feature, we'll automatically add them to the References table. This is great when you have tasks or Docs that are related, but not necessarily dependent on each other, and want to keep track of where they're being discussed
What you'll need
Relationships are available on any ClickUp Plan.
Anyone, including guests, can use Reference Relationships.
Note: You need permission to view a task or Doc in order to create a reference or view it in the References table.
References in tasks
When someone mentions a task or Doc in a different task with the @mention feature, we'll automatically add it to the References table–this is great when you have tasks or Docs that are related, but not necessarily dependent on each other.
To see where else your task has been referenced, scroll to the Relationships section in a task, and find the References table.
For example, let's say you mention the task Budget review
in the description of a task called Monthly finances
. In the References table of the Budget review
task, you'll see a clickable link to the Monthly finances
task, so you can easily keep track of the places it's been mentioned.
If the task doesn't have any mentions, the References table will not display.
Note: If you're using the Custom Relationship option, we'll also display the tasks in the References section with a label indicating what Relationship it's included in.

References in Docs
When someone mentions a Doc within another Doc or a task, we'll automatically add that task or Doc as a Reference.
To see References in a Doc, open the right sidebar and select Relationships & References.
