Page with sidebar menu
A page with a menu as a sidebar (as seen in the online preview), is a simple page which has a custom sidebar (created in the Theme Options panel) assigned. That custom sidebar (widget area) simply contains a custom menu, created just like any other menu.
To show icons in the menu, you have to add custom classes to each menu item. To this by first enabling the CSS Classes (from the Screen Options - top right corner). Then, use CSS names for the icons as classes. The full list of icon names can be found at this link. You need to add the prefix krown-icon- to each name, so for example, umbrella would become krown-icon-umbrella, and so on..
