Navigation Collapsed - More than 2 levels deep

[wp_dev_themeco]

We’re working with a client, who has a lot of content on his website organized in pages.
The pages are nested up to 4 levels (see screenshot).
It seems the navigation-collapsed doesn’t support more than 2 levels of indentation. Is this the right observation? Or did we miss something?
Is there documentation on how we can indent the levels below 2?

Hello WP Dev,

Please add this code in the Element CSS of the Navigation Collapsed element:

$el.x-menu.x-menu-collapsed li .sub-menu {
    margin-left: 2em;
}

I have also taken a note of this so that the indent will take effect to the deeper level navigations. However, we cannot provide any ETA if a feature will be added but you can use this as a workaround.

Hope this helps.
