    ContentItem contentItem = Model.ContentItem;
    var link = contentItem.Content["LinkMenuItemPart"];
}

Mark active item in a menu

Some times you need to set a menu item as active if it is the currently displayed one. Because menus are cached, this must be done from javascript. OrchardCore.Menu module provides a script to help you with that.

function activateLinks(options,cb)

Parameter	Description
options: {class:'active',selector:null,traverse:0}	Use class to define what class you want to add to the parent of the anchor tag that has the current url as href. If you want to apply it to a child, set the selector property. Use the traverse to a positive number in order to seek a less specific url in the menu tree then the currently displayed on. ex. If you have a link to '/todo-items' in menu and you have navigated to '/todo-items/Create', it will try to find the item with traverse item less segments in the menu and activate it.
cb: function( items )	If it finds an active item, the call back is hit for extra configuration. ex. Expand a menu item if the active one is nested.

activateLinks usage in Layout file

LiquidRazor

...
{% script at:"Foot", src:"~/OrchardCore.Menu/Scripts/activate-links.min.js", debug_src:"~/OrchardCore.Menu/Scripts/activate-links.js" %}
...
    <resources type="Footer" />
...
    <script>
        (function ($) {
            $('#mainNav').activateLinks({ selector: 'a', traverse: 2 }, function (items) {
                var parents = $(items).closest(".has-treeview")
                parents.addClass('menu-open');
            });
        })(jQuery);
