How to hide MODX menu item?

Question

CMS

Good day!
There is a site on ModX Evolution and 2 menus: horizontal and vertical. There is a checkbox in the admin panel of the category "Show in menu"

<input name="hidemenucheck" type="checkbox" class="checkbox" onclick="changestate(document.mutate.hidemenu);">

But it only works for the horizontal menu, which is controlled by the wayfinder module, in the vertical one - the categories are shown as they are.
I want to add a condition that if the hidemenu checkbox is set to 1, then display the code of the menu item. If not in the value 0, then do not display the code of this menu item. How to implement it?
