I am using the MUP (Multi Url Picker) to build my navigation.
This requires us to use the <Link> object vs the <IPublishedContent> . That said I am trying to get the current URL or page and adding the "active" CSS class to it. When I try to use the "IsAncestorOrSelf()" like in every post suggested in Our, but because I am using the MUP, the "IsAncestorOrSelf()" is not working.

I get the error: 'Link' does not contain a definition for 'IsAncestorOrSelf' and no accessible extension method 'IsAncestorOrSelf' accepting a first argument of type 'Link'

My code is below:

  @{ var topLevelNavItemLink = topLevelNavItem.GetPropertyValue<Link>("navigationElementLinkMUP");}

@if (topLevelNavItemLink != null)
{
    @*This doesn't work using IsAncestorOrSelf()*@
            <a href="@topLevelNavItemLink.Url" class="navItem" @(topLevelNavItemLink.IsAncestorOrSelf(Model) ? "active" : null)>
                    @topLevelNavItemLink.Name
            </a>

}
