Details

You can bind the directive instance to a template variable through the adfFavorite reference, which also lets you add extra styling to the element:

<button
    mat-menu-item
    #selection="adfFavorite"
    [ngClass]="{ 'icon-highlight': selection.hasFavorites() }"
    [adf-node-favorite]="documentList.selection">
    <mat-icon [ngClass]="{ 'icon-highlight': selection.hasFavorites() }">
        {{ selection.hasFavorites() ? 'star' : 'star_border' }}
    </mat-icon>
</button>

The directive behaves as follows:

• If there are no favorite nodes in the selection, then all are marked as favorites
• If there are one or more favorite nodes in the selection, then only those that are not favorites are marked
• If all nodes in the selection are favorites, then they all have their favorite status removed

See the Demo Shell for examples of usage.
