The Joined List column lets you join values from a column or multi-relation into a single cell.
Here we can see the column gathering all the values in the Name column and joining them into one long string of text.
But often joining the values of a multi-relation may make more sense. In the image below the Joined List column is pulling values from a relation and bringing back a simple list of ingredients. With all these values in one cell, we can now display this list simply in a text component.

The Joined List column also allows you to choose how you separate these different values. By default, all values are separated by ", " but you can add whatever you want as a separator – including a value from another column.
