Add a unique class to an element within a main component

Within our application root, there exists a sidebar consisting of a list. We utilize uiSrefActive to apply an active class to the selected list item upon clicking it. However, once you navigate away from that component, the original list item loses its active status. My goal is to retain the active class on the list element when transitioning from the initially loaded component to another component (which would logically be a child of the previous one). At the top of the page, we also have a breadcrumb component where the first parent always corresponds to the component requiring the active state in the list. Is there a possible solution for achieving this desired functionality?

Answer №1

Managing your navigation stack can be achieved in a few different ways.

  1. One approach is to develop a service to monitor your navigation stack. This means that when you choose an item from the sidebar, its active status and breadcrumbs would rely on the service for tracking.

  2. Alternatively (and in my opinion, the better way), you can utilize Angular routing. This method assumes that your navigation is structured around Angular's Router.

<h1>Angular Router</h1>
  <nav>
    <a routerLink="/crisis-center" routerLinkActive="active">Crisis Center</a>
    <a routerLink="/heroes" routerLinkActive="active">Heroes</a>
  </nav>
<router-outlet></router-outlet>

routerLinkActive will add a 'active' class to the a element if the specified routerLink is currently active.

You can also access the active link programmatically from your controllers by using the ActivatedRoute provider.
