At the moment, I have found that this can be done for category 1.
Category 1
--- Category 2
----- Category 3
In the first category, links from category 2 and 3 will be displayed. But how to make category 2 display links from category 3 too.
P.S. A small error In the language file Russian.lng - remove unnecessary space in a variable.

And in the file: displaylinks.tpl
It may be worthwhile to set conditions so as not to display an empty header (UX / UI) when the menu items are somehow hidden (no rights, etc.)
<IF {CATCANSUBMITLINKS} or {SWITCH_DENIALPAGE}>... else ... if
In code:
<div class="toolscolumn">
<div class="box panel panel-default bg-light">
<div class="boxtitle panel-heading card-header bg-primary text-white" onclick="wsn_minmax('actionsbox')">{FUNC_SHOWICON[cloud-upload]} <h3 class="panel-title card-title">{LANG_DISPLAYLINKS_ACTIONS}</h3></div> |
