Hey PV,
the icon menu in the left part of the demo uses the portfolio-related “tag” taxonomy I’ve mentioned above – once you have the tags (Portfolio -> Tags admin menu), you can create the icon menu items in the “Icon Menu” tab of the Theme Options panel. For more information and screenshots, please see pages 3-4 of the theme manual.
Should you have problems with the icon menu items, do not hesitate to contact me!
Sincerely,
Andrii / Satori Studio
