How to make a three-level menu bootstrap 3 to Wordpress template (Halt! Hate!)?

Good afternoon, colleagues.
Tried all the buckets and crutches, and so decided to turn to you for help, because you start to quietly hate in Wordpress multi-level menu.
Well, from words to deeds:
TK:
this:
-CMS Wordpress
-bootstrap 3

task:

NO plugins, handles, bootstrap 3 to make a three-level menu (that is, from the horizontal menu falls 2 level submenu, and FROM the drop-down submenu drops another 3(!) level).

In fact it is necessary to integrate like this:


What I have done:

I integrated the layout, similar to the example snippet, but the level three (example of snippet levels with text
Action [Menu 1.2]
Dropdown [Menu 1.2]

not vypaivajut?

I love it, pliz. And then I boil already:)

If it was considered where question-throw the link.
On the tutorial.
Video.

Digging Google and Yandex, YouTube, helped only to integrate dwuhosnovny.
I don't know where I missed.

Solution
So what?

removed

In the end, what does not, is not clear!! Nothing falls out??
Here it is? - 'depth' => 4,
Yes, it is a menu. Almost to the tee. Where to find code? - charlotte.Erdman commented on June 5th 19 at 21:44
so what's the issue then? not drop any level? Or don't get a third level? or he does not appear at all? Or everything falls as it should , but crap-on one side, street Pushkin, the house Kolotushkin? )) - ted_Leuschke commented on June 5th 19 at 21:47
I have that same layout

when integration does not drop the level 3
that is only possible to get a submenu, and the submenu nothing falls out.
that's the problem - charlotte.Erdman commented on June 5th 19 at 21:50
the fact is that everything I have done without any of valkanov and similar scales!!)))
Here is the working code, nothing unusual:
wp_nav_menu( array(
 'theme_location' => 'header_menu',
 'menu_id' => 'ul-drop',
 'container' => false,
 'depth' => 4,
 'link_before' => '<span>',
 'link_after' => '</span><span class="menu_toggler"></span>',
) );

Have not heard the answer to the question - the THIRD level is displayed on the front or not???!!! The question is not about the FALLS OR NOT, and generally does, albeit in a hidden form. I think the problem is CSS+JS, not in any walkera)))
Just long had to provide a link which would not have been a secret website, to sit and suck his paw for a long time.... Well, or a piece of source code... - ted_Leuschke commented on June 5th 19 at 21:53
and something and for example there is no third level.... Ah, there it is necessary to log.. well done, a good example given))) - ted_Leuschke commented on June 5th 19 at 21:56
proved solution validation JS. - charlotte.Erdman commented on June 5th 19 at 21:59

What exactly were you doing and what stumbled? From bootstrap is by default cuts the third level?

Set menu custom walkerto lead him to bootstrapurl. And behavior the third level are themselves described on a css/js.
tough question, never 3ur menu, it was not possible to do))
I'll try your option - charlotte.Erdman commented on June 5th 19 at 21:46

integration interested in her.
the layout itself works fine, but integration appears only 1 level,
and we must all

Hello!
Not looking for online? Just, there are several options to try.
