# Layout List - Campaign

Create a Campaign containing a list of ordered Layouts so that they play in a controlled sequence. Think of a Layout as a single slide in a presentation deck, a Layout List Campaign is the entire presentation.

## Creating a Layout List Campaign

- Go to Campaigns under the Design section of the main CMS menu.

- Click the Add Campaign button.

- Use the Type drop down and select Layout List.

- Give your Campaign a Name for easy identification in the CMS.

- Optionally use the checkbox to enable Cycle Based Playback, and provide a number to determine how many ‘plays’ a Layout should have before moving onto the next Layout in the Campaign.

> If a 2 was set as the Play Count, the same Layout would be shown twice each Schedule loop before moving onto the next Layout in the sequence.

- Leave Cycle based playback blank and use the List Play Order menu to select how Layouts will play when scheduled concurrently with another Campaign with the same Display Order:
- Select Round Robin to interleave Layouts from each Campaign or Block to play Layouts in their set sequence from one Campaign before moving onto the next Campaign.
- Click to Save.

On saving, the form will re-open with an additional Layouts tab:

- Select the Layouts which should be added to the Campaign.

- Use the `+` icon to for each Layout to add.

- Added Layouts will be shown at the top of the Edit Campaign form.

Layouts can be re-ordered from here by drag and drop to ensure they play in the correct sequence.

Use the `-` icon for an added Layout to remove from the Campaign.

- Click to Save.

## FAQs

Is there an easy way to create multiple Campaigns?

Make copies of selected Campaigns by using the row menu in the Campaign grid. Once a copy has been created use the row menu to select Edit to make changes to the Layout selection.

Can I assign Layouts to a Campaign from anywhere else in the CMS?

Directly assign Layouts to Campaigns from the Layout grid. Use the row menu for a selected Layout and click Assign to Campaign. Once added the Layout will be added at the end of the sequence of other added Layouts by default.
