# Grouping Lists

Sometimes, you need to group lists together. Let's use the [Trello Public Roadmap board](https://trello.com/b/nC8QJJoZ/trello-development-roadmap) and Cumulative Flow chart as examples.

As you can see, there are Live lists created for every quarter. We need to unite them into a single group, because we're interested in total feature progress, rather than tracking separate cards.

This can be done using the `CASE WHEN` statement. So, we need to select 'List' in the Color panel, and change the calculation to the following:

`CASE WHEN CONTAINS([List], 'Live') THEN 'Live' ELSE [List]`

We then need to rename the Axis Label to 'List', since it is currently auto-named.
