How to use the submenu label in the dedecms secondary menu

How to determine the submenu label in the dedecms secondary menu?

I recently worked on a project that required the use of the secondary menu of dedecms. In it, I needed to determine which first-level menus had submenus. Some of them would display pop-up drop-down boxes, and others would not. You can Use js to implement it, but if you haven’t used js for a long time, you will almost forget it, so you can simply use dedecms’ own tags to make a judgment. The code is as follows.

The code is as follows:

<ul id="nav"> 
<li><a href="{dede:global.cfg_cmsurl/}/">Home</a></li> 
{dede:channelartlist typeid={dede:field.typeid/} 
<li> 
<a href="{dede:field name=&#39;typeurl&#39;/}" class="level">{dede:field name=&#39;typename&#39;/}</a> 
{dede:global name=&#39;itemindex&#39; runphp=&#39;yes&#39;}if(@me==1)@me="<ul class=&#39;nav-submenu&#39;>"; else @me=&#39;&#39;;{/dede:global} 
{dede:channel type=&#39;son&#39;} 
<li class="level0 nav-[field:global name=autoindex runphp="yes"]@me=@me+1;[/field:global]"><a href="[field:typelink/]"><span>[field:typename/]</span></a></li> 
{/dede:channel} 
{dede:global name=&#39;itemindex&#39; runphp=&#39;yes&#39;}if(@me==1)@me="</ul>";else @me=&#39;&#39;;{/dede:global} 
</li> 
{/dede:channelartlist} 
</ul>

The itemindex is required for the top-level column. It is known that only the first column has a drop-down menu, and the itemindex is incrementally increased from 1, so when itemindex=1 It is the column that needs to display the secondary menu
