How do I hide a column on a List?

You can hide & unhide columns on your List.

Note, these changes will apply to your whole team, not just your view.

Click the three dots on the top-right of your List.

Then select "Columns".

Click the eye icon next to the column(s) you want to hide.

Click "Save & Close".

To unhide, simply click the eye again, and click "Save & Close".
