Hi there,
To create a DFP Ad that uses MRAID by specifying one of its Device Capabilities as MRAID v1 or MRAID v2 (under Targeting > Devices) when you create a new line item, and create its creative from a Third-Party or Custom creative template. Then, under the creative's setting, you specify your custom HTML code to be displayed as the creative of the ad, which may include your MRAID implementations.
You can learn more on how to use MRAID on your DFP Ads, as well as check out some sample code snippets
here. You can also read more about the specifications of MRAID in
our official help site.
