Hi Pughe,

These are the settings to make the portfolio gallery same as that page. http://prntscr.com/mwhfdj

Hey Pughe,

There are options in the header in Theme Options or in the page settings, where you can set your header container to On or Off.

Feel free to ask for anything you need.

No worries Pughe, feel free to ask for anything you need

Simply, set the header position to absolute and that will be fixed.

Kind Regards

Edit the portfolio item and at the portfolio item settings you will spot a tab called Header, change the position to absolute and everything will be set as in the demo. http://prntscr.com/mwyrr7
