You can group together static and dynamic lists into a folder when they don’t have any logical grouping/categories or relationships to each other.
To create a new folder, simply click the 'plus icon' button on the left-hand side menu of your Funnel dashboard and select 'folder.'
Once you've created your folder, you can group your lists into the folder by selecting the options menu on the list and choosing 'move list'.
You'll then be presented with a modal to 'Move list to folder', and from the dropdown you can choose a folder. Alternatively, you can 'Create new folder' from the window.
