To add your own navigation capability, create a Lightning Component that extends forceCommunity:navigationMenuBase. The code snippet to get started is given in the following code. Note that {!v.menuItems} automatically adds the menuItems, which was configured in the navigation menu by the community admin. Take a look at this code block:
<aura:component extends="forceCommunity:navigationMenuBase"> <div class="slds-grid slds-grid--vertical slds-navigation-list--vertical"> <ul onclick="{!c.onClick}"> <aura:iteration items="{!v.menuItems}" var="item"> <li class="{!item.active ? 'slds-is-active' : ''}"> <a href="javascript:void(0);" data-menu-item-id="{!item.id}" class="slds-navigation-list--vertical__action slds-text-link--reset"> ...
