Hello,
Do you mean you want the same slider effect on the header as on the demo https://www.8theme.com/demo/royal/?page_id=16411&et_styles=0-1-1-8-0-1 ?
If so you need edit your home page and select the slider in “Show revolution slider instead of breadcrumbs and page title” section at the bottom. Then choose transparent header type in Theme Options > Header > Header Type 2.
Thank you.
Regards,
Eva Kemp.
