The trick is to make the recursive call before producing any output.
There's alot that could be done to clean up your stylesheet, but with
minimal changes to it, here's a version that should do what you want:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.1"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:param name="url"/>
  <xsl:output method="html" encoding="ISO-8859-1"/>

  <xsl:template match="/dfile">
  <script language="javascript">
    function loadMenus() {
        <xsl:call-template name="sub_menus"/>
        writeMenus();
    }
  </script>
  <script language="JavaScript">loadMenus();</script>
  </xsl:template>

  <xsl:template name="sub_menus">
    <xsl:for-each select="df_data_row">
        <xsl:if test="child::df_data_row">
        <xsl:call-template name="sub_menus"/>
        window.mnu_<xsl:value-of select="document_id"/> = new
Menu('<xsl:value-of select="name"/>','Verdana, Arial, Helvetica,
sans-serif',11,'ffffff','000033','cce3f8','ffffff','left','top',2,2,300,2,1,
true,true,true,0);

<xsl:call-template name="menu_items"/>
        </xsl:if>
    </xsl:for-each>
  </xsl:template>

<xsl:template name="menu_items">
  <xsl:for-each select="child::df_data_row">
    <xsl:choose>
        <xsl:when test="child::df_data_row">
          mnu_<xsl:value-of
select="parent::df_data_row/document_id"/>.addMenuItem(mnu_<xsl:value-of
select="document_id"/>,"document.location.href='index.php?pg=<xsl:value-of select="document_id"/>'");
        </xsl:when>
        <xsl:otherwise>
          mnu_<xsl:value-of
select="parent::df_data_row/document_id"/>.addMenuItem("<xsl:value-of
select="name"/>", "document.location.href='index.php?pg=<xsl:value-of
select="document_id"/>'" );
        </xsl:otherwise>
   </xsl:choose>
  </xsl:for-each>
</xsl:template>

</xsl:stylesheet>
