如何使xslt导航栏显示下拉列表

Question

我们正在使用teamsite CMS使用bootstrap开发导航栏。当我们在本地环境中使用HTML开发导航栏时，下拉列表工作正常。但是，当我们使用XSLT进行部署时，下拉列表不会出现。我们已尝试增加z-index等。但它不起作用。下拉列表是开启和关闭。内容不显示。有什么想法吗？

    <xsl:param name="category" />

    <nav class="navbar navbar-default" id="navbar" role="navigation" data-omni_group="top_nav_all">

        <xsl:choose>
            <xsl:when test="$category ='landing-page'">
                <xsl:attribute name="class">navbar unmovable landing-shift-right</xsl:attribute>
            </xsl:when>
            <xsl:otherwise>
                <xsl:attribute name="class">navbar navbar-default</xsl:attribute>
            </xsl:otherwise>
        </xsl:choose>
