I have a problem with the PrimeFaces MegaMenu, I can not leave it upright. I am making a code to test, which follows below:
<p:megaMenu orientation="vertical" style="margin-top:20px">
<p:submenu label="MENU" icon="ui-icon-check">
<p:column>
<p:submenu label="Menu.1">
<p:menuitem value="Opcao.1.1" url="#" />
<p:menuitem value="Opcao.1.2" url="#" />
</p:submenu>
<p:submenu label="Opcao.2">
<p:menuitem value="Opcao.2.1" url="#" />
<p:menuitem value="Opcao.2.2" url="#" />
<p:menuitem value="Opcao.2.3" url="#" />
</p:submenu>
</p:column>
<p:column>
<p:submenu label="Menu.2">
<p:menuitem value="Opcao.4.1" url="#" />
<p:menuitem value="Opcao.4.2" url="#" />
</p:submenu>
<p:submenu label="TV.5">
<p:menuitem value="Opcao.5.1" url="#" />
<p:menuitem value="Opcao.5.2" url="#" />
<p:menuitem value="Opcao.5.3" url="#" />
</p:submenu>
</p:column>
</p:submenu>
</p:megaMenu>
