The Sub header on the Formats page
On the left of the sub header there are two buttons, 'Preview URLs' and 'Format Groups':
* Preview URLs - This link will take you to the '[Edit preview URLs in showcase](/ad-management/showcase.md)' page
* Format groups - This link will take you to the Format [Custom Groups management](/creating-ads/designing-your-ad-in-the-fluid-ad-creator/how-to-use-formats-and-layouts.md) page
On the far right of the sub header is a 'Create New Format' button. This will launch the [Format creation process](/creating-ads/designing-your-ad-in-the-fluid-ad-creator/how-to-use-formats-and-layouts.md). In addition, there is also a search bar which can be used to find a specific Format by name, as well as a sort dropdown which can be used to sort the list of Formats.
## List of Formats
List of Formats on the Formats page
This is a list of all of the Formats you have access to in the Fluid Ad Creator. The list of Formats has 3 columns of info:

* **Actions** -
