Hey Chelawonk,
the theme will automatically substitute the icon menu filter triggers with links to respective portfolio tag pages once you move away form the portfolio page (e.g. if you click on the “Features” top menu item in the demo and then click on any of the icon menu items, it will not bring you to the front page, but to a tag archive page, which you can see by the URL). In order for this mechanism to work, please make sure that the “Filter” field in the icon menu items in the “Icon Menu” tab of the Theme Options panel contains the name of the portfolio tag (it’s not case-sensitive).
Sincerely,
Andrii / Satori Studio
