Multi-lingual navigation. Help needed!

Hi there!
I’m trying to make Ghost work for me to make a blog with two languages. Some things I’ve managed, but still struggling with some others. One of them, is that I want to use #has to check for either the tag #no or that the slug=“no” so I can do different things if I’m on the Norwegian part of the blog (as opposed to the English part).

I’m new to programming myself, but got some help from a friend who works with it and we made something he thought would work, but doesn’t (he doesn’t know Handlebars in specific).

Can anyone tell me why this doesn’t work?
I’m using Ghost(Pro), btw, so everything is installed there and should be the newest version etc.

We’ve made this code for the navigation:

<ul class="nav-list u-plain-list">

 {{#has slug="no" tag="#no"}}
    <li class="menu-item menu-item-{{slug}}{{#if current}} menu-item-current{{/if}}"><a class="menu-item-link"
                href="https://havn.ghost.io/no/">Hjem</a></li>
    <li class="menu-item menu-item-{{slug}}{{#if current}} menu-item-current{{/if}}"><a class="menu-item-link"
                href="https://havn.ghost.io/om_og_kontakt/">Om</a></li>
    <li class="menu-item menu-item-{{slug}}{{#if current}} menu-item-current{{/if}}"><a class="menu-item-link"
                href="https://havn.ghost.io/">Engelsk</a></li>
{{else}}
    <li class="menu-item menu-item"-{{slug}}{{#if current}} menu-item-current{{/if}}"><a class="menu-item-link"
                href="https://havn.ghost.io/">Home</a></li>
    <li class="menu-item menu-item"-{{slug}}{{#if current}} menu-item-current{{/if}}"><a class="menu-item-link"
                href="https://havn.ghost.io/about_and_contact/">About</a></li>
    <li class="menu-item menu-item"-{{slug}}{{#if current}} menu-item-current{{/if}}"><a class="menu-item-link"
                href="https://havn.ghost.io/no/">Norwegian</a></li>

{{/has}}

</ul>

However, it always goes to the {{else}}-part. What we hoped was for the site to look for EITHER “no” in the slug AND/OR tag="#no" and then display the top menu items.

Any help?
Thanks!
