    <p>I am creating a menu for the MVC music store application. Currently it looks like this <img src="https://i.stack.imgur.com/t0yDn.png" alt="As you can see I have the index view CSS selected not the About view"></p> <p>As you can see I have the Home sub level menu selected when in fact I am on the About View.</p> <p>I used Darins example for the main menu and created a helper class which looks like this.</p> <pre class="lang-cs prettyprint-override"><code>public static MvcHtmlString MenuLink(this HtmlHelper helper, string linkText, string actionName, string controllerName) { string currentAction = helper.ViewContext.RouteData.GetRequiredString("action"); string currentController = helper.ViewContext.RouteData.GetRequiredString("controller"); //modified this to work whenever a view of the controller is selected //if (actionName == currentAction &amp;&amp; controllerName == currentController) if (controllerName == currentController) { return helper.ActionLink( linkText, actionName, controllerName, null, new { @class = "active" }); } return helper.ActionLink(linkText, actionName, controllerName); } </code></pre> <p>Note I did slightly change the code as I wasn't interested in action name. I found this limited me and the main menu wouldn't add the active CSS state where I wanted.</p> <p>So that works perfect for the top level menu however I am a little stuck with the sublevel menu. My html consists of 2 UL tags like</p> <pre class="lang-html prettyprint-override"><code> &lt;nav id="main-nav"&gt; &lt;ul&gt; &lt;li&gt;@Html.MenuLink("Home", "Index", "Home")&lt;/li&gt; &lt;li&gt;@Html.MenuLink("Store", "Index", "Store")&lt;/li&gt; &lt;li&gt;@Html.MenuLink("Cart", "Index", "ShoppingCart")&lt;/li&gt; &lt;li&gt;@Html.MenuLink("Admin", "Index", "StoreManager")&lt;/li&gt; &lt;/ul&gt; &lt;/nav&gt; &lt;/div&gt; &lt;div id="page-subheader"&gt; &lt;div class="wrapper"&gt; &lt;nav id="sub-nav"&gt; &lt;ul&gt; &lt;li&gt;@Html.SubMenuLink("Home", "Index", "Home")&lt;/li&gt; &lt;li&gt;@Html.SubMenuLink("About", "Index", "Home/About")&lt;/li&gt; @* &lt;li class="active"&gt;&lt;a href="@Url.Content("~")"&gt;Index&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="@Url.Content("~/Home/About")"&gt;About&lt;/a&gt;&lt;/li&gt;*@ &lt;/ul&gt; &lt;/nav&gt; &lt;input placeholder="Search..." type="text" name="q" value="" /&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>Pretty standard HTML I have also tried to create another helper like:</p> <pre class="lang-cs prettyprint-override"><code>public static MvcHtmlString SubMenuLink(this HtmlHelper helper, string linkText, string actionName, string controllerName) { string currentAction = helper.ViewContext.RouteData.GetRequiredString("action"); string currentController = helper.ViewContext.RouteData.GetRequiredString("controller"); if (controllerName == currentController) { return helper.ActionLink( linkText, actionName, controllerName, null, new { @class = "active" }); } return helper.ActionLink(linkText, actionName, controllerName); } </code></pre> <p>But I don't really know what to do next. If I put a break point on the code I can see <code>currentAction</code> is been returned as <code>About</code> and <code>currentController</code> is been returned as <code>Home</code>, I'm just a little unsure how to add the logic apply the active CSS class to the submenu.</p> <p>Can some please help?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
