<br><font size=2 face="sans-serif">&nbsp; &nbsp;I use class QPopupMenu to create a 3-level submenu, codes below:</font>
<br>
<br>
<br><font size=2 face="sans-serif">&nbsp; &nbsp; firstMenu = new QPopupMenu(this,&quot;1&quot;);</font>
<br>
<br><font size=2 face="sans-serif">&nbsp; &nbsp; secondMenu = new QPopupMenu(this,&quot;2&quot;);</font>
<br><font size=2 face="sans-serif">&nbsp;<br>
 &nbsp; &nbsp;thirdMenu = new QPopupMenu(this,&quot;3&quot;);</font>
<br>
<br><font size=2 face="sans-serif">&nbsp; &nbsp; thirdMenu-&gt;insertItem(&quot;test31&quot;, 100);</font>
<br><font size=2 face="sans-serif">&nbsp; &nbsp; thirdMenu-&gt;insertItem(&quot;test32&quot;, 101);</font>
<br>
<br><font size=2 face="sans-serif">&nbsp; &nbsp; secondMenu-&gt;insertItem(&quot;test21&quot;, 102);</font>
<br><font size=2 face="sans-serif">&nbsp; &nbsp; secondMenu-&gt;insertItem(&quot;test22&quot;, thirdMenu,103);</font>
<br>
<br><font size=2 face="sans-serif">&nbsp; &nbsp; firstMenu-&gt;insertItem(&quot;test11&quot;, secondMenu,104);</font>
