Hi,
To add the banner to Page:
- If you use one banner for all pages: You go to Theme Options -> Pages -> Page Title -> add "Page title background". http://prntscr.com/hd53uu
**** If you use a private banner for Shop Page*****
- Archive Product: You go to Theme Options -> Shop -> Archive Product -> Archive Product Title -> add "Archive product title background". http://prntscr.com/hd56q7
- Single Product: You go to Theme Options -> Shop -> Single Product -> Single Product Title -> add "Single Product Title Background". http://prntscr.com/hd57py
**************
Currently, you use the shortcode of Visual Composer to add the banner. To have the banner full page:
You click row edit:
General -> Row Stretch -> set "Default". http://prntscr.com/hd5bfw
Yolo Option -> Layout -> Full width. http://prntscr.com/hd5c56
Hope it helps!.
Best regard,
