Hi Geoffrey,

Notice the conditional <xsl:when test="@enabled = 1">, and the tag <xsl:otherwise> which specifies only the tab icon and name to be shown. I just wrote an <a> tag (with no actual link) to get the same class applied as in the enabled tabs. The whole code reads:
<xsl:when test="@enabled = 1">
          <a href="{@url}">
            <span>
                <xsl:if test="@icon">
                    <img src="{@icon}" class="mmIcon" />
                </xsl:if>
                <xsl:value-of select="@text" />
                <xsl:if test="node and $nodeType = 'root'">
                    <img src="{$ManifestPath}/Images/child-arrow.png" class="mmArrow" />
                </xsl:if>
            </span>
          </a>
        </xsl:when>
        <xsl:otherwise>
          <a href=" void();">
            <xsl:if test="@icon">
              <img src="{@icon}" class="mmIcon" />
            </xsl:if>
            <span>
              <xsl:value-of select="@text" />
              <xsl:if test="node and $nodeType = 'root'">
                <img src="{$ManifestPath}/Images/child-arrow.png" class="mmArrow" />
              </xsl:if>
            </span>
          </a>
        </xsl:otherwise>

I'm sure this can ve solved in a much more elegant way, but this is working ;-)

Best regards,
Francisco
