The Co-Branded Collateral module allows you to upload content to your portal and designate it as co-brandable by your Partners. The tool lets you define specific Content Areas where Partners can customize the piece by adding their logos, contact information, and text about their company.
(New Asset with Content Areas defined)
Once you've defined your Content Areas, you can publish the Asset making it visible to Partners.
(Asset Publish Status)
(Published Assets - Partner View)
Partners can then co-brand the Asset by updating the Content Areas with their logo and contact information. 
(Logo Content Area - Partner View)
When they finish updating the Content Areas, the system generates a downloadable co-branded Asset for the Partner that is stored in the "Generated Collateral" section of the module.
