SAP Portal 7.3 Masthead hiding

Hi,

Can I hide the masthead without the Masthead - Menu Bar.

I want to keep the Masthead- Menu Bar.

But I want to hide the Masthead. The below image will make it clear.

I can hide all the individual elements (logo, search, new session, sap store, log off) but still a white row is left

as shown below. I want to hide that white row.

Thanks

Arindam
