    Need a little razor help ...

    I have the following code:

    <li class="@(isActive ? "active" : "")">
    <href="@node.Url">@node.Name</a>
    </li>

    But this gives kinda dirty code since all other LI than the active on will get an empty class attribute.

    I would solve it like this with XSLT:

    <xsl:variable name="classes">
        <xsl:if test="@id = $currentPage/@id">
            <xsl:text>active </xsl:text>
        </xsl:if>
        <xsl:if test="position() = 1">
            <xsl:text>first </xsl:text>
        </xsl:if>
        <xsl:if test="position() = last()">
            <xsl:text>last </xsl:text>
        </xsl:if>
    </xsl:variable>
    
    <li>
        <xsl:if test="normalize-space($classes)">
            <xsl:attribute name="class">
                <xsl:value-of select="normalize-space($classes)" />
            </xsl:attribute>
        </xsl:if>
        <a href="{umb:NiceUrl(@id)}">
            <xsl:call-template name="pagename" />
        </a>
    </li>

    And how to I handle the multiple classes from the XSLT in the Razor example ?

    I hope that anyone can answer my question ...

    Just move the class="" into the if statement?

    It doesn't really matter that it has an empty class, but you could just make your code a little uglier: 

    <li @(isActive ? "class=\"active\"" : "")>
            <a href="@node.Url">@node.Name</a>
    </li>

    Thanx alot guys.

    You're right that it doesn't really matter, but it doesn't look nice with the empty class attributes.

    How do I add a second class like 'first' or 'last' without overwriting the one 'active' currently assigned ?

    I would just change it up a little bit then (untested):

    @{
    var cssClass = ""; if (isActive) { cssClass = "active"; } if (node.IsFirst()) { cssClass += " first"; } if (node.IsLast()) { cssClass += " last"; } var liClass = ""; if(cssClass != string.Empty) { liClass = string.Format("class=\"{0}\"", cssClass.Trim()); } } <li @Html.Raw(liClass)> <a href="@node.Url">@node.Name</a> </li> 

    A few notes: I do the "Trim()" there because a node can be first or last, but not active, so you would get class=" first" instead of class="first".

    Because there is quotes in the string, Razor does automatic escaping, so we need to do Html.Raw to get the unescaped quotes back.
