How to create this type of menu in WordPress?

I don't know how to do it either :D

The only thing I know is on how to make one menu, without breaks, like this one.

<?php
                $args = array(

                   'menu_class' => 'header__navigation__list',
                   'walker'     =>  new Bem_Menu_Walker(),
                   'container' => 'false'
                );
                wp_nav_menu( $args );
            ?>

Though on how to make a menu like that one, which the HTML looks like this

 <div class="c-mainNavigationPanel--menusWrapper">
            <nav class="c-mainNavigationPanel--menuAccount">
                <ul class="l-mainMenu">
                    <li class="l-mainMenu--item c-mainNavigationPanel__item btn--join"><a href="join.html">Join</a></li>
                    <li class="l-mainMenu--item c-mainNavigationPanel__item" ><a href="language.html">English</a></li>
                </ul>
            </nav>

            <nav class="c-mainNavigationPanel--menuContainer">
                <ul class="l-mainMenu">
                    <li class="l-mainMenu c-mainNavigationPanel__item--active"><a href="index.html">App</a></li>
                    <li class="l-mainMenu c-mainNavigationPanel__item"><a href="blog.html">Blog</a></li>
                    <li class="l-mainMenu c-mainNavigationPanel__item"><a href="faq.html">FAQ</a></li>
                    <li class="l-mainMenu c-mainNavigationPanel__item"><a href="contact.html">Contact</a></li>
                    <li class="l-mainMenu c-mainNavigationPanel__item is-desktop-hide"><a href="join.html">Join</a></li>
                    <li class="l-mainMenu c-mainNavigationPanel__item is-desktop-hide"><a href="languages.html">English</a></li>
                </ul>
            </nav>
            </div>

So there is also a menuAccount with the same Join and ENglish, which is in the menuCOntainer.

I have no idea how to make a menu like this to work in WP.

Good point, I didn't realize it wasn't wordpress. You'd be right, a new Walker class should be used to create the desired html markup.

You could also probably modify the html that wordpress gives, you, but while more difficult to start, I think a Walker class is the better option here.

Could you lead me on how should I do this? Because I'm not too sure :D I'm not too experienced in WP. I never did any different menu than the default one.

In CSS here as you can see, or HTML, yeah, I'm getting more experience in that, and you know it lol

So, how is that I should do this with Walker? I'm not really sure how this supposed to look in the code.

Sorry, not really. I haven't done much with Walker classes in a long time, and I no longer build wordpress sites. I just know what they can do, and are intended for. If i remember there was some extensive documentation about Walker classes on the official codex.

Wow. Really? I know you're a human now. Usually you knew everything : D I suppose you just have a very very strong foundation , and now you're just specializing in few directions.

Okay, I'll try to see. Thank you :)

Ahh xd I can't see a damn thing about this menu. Think I might just live WP atm.

Think it's better to learn PHP.. so I can do whatever and it can serve me in the long term run, instead of jumping to WP when I need to and trying to do stuff who knows what lol whithout putting in time to properly learn WP : p I don't know.

Need to learn more in depth PHP in general and JS, but think I live JS for now, I can somewhat do what I want in most cases with JS.
