How to get navigation item active?

Hi everyone, hope someone can help with as I’m having a working but not sustainable solution for a navigation menu in the header.

I’ve been building the navigation based on a structural way from Tailor. It’s the one from the latest demo theme.

As you can see, a class active will be added based on the meta_title of the page.
This is far from ideal and therefore I looking for a sustainable solution. And hope one of you could help me out in this way.

Good to know is that most of my pages are build in Tailor (structural) way, similar to the menu.

Thanks!

CODE NAVIGATION

{% set activeNavLink = activeNavLink|default(this.page.id) %} {# leftover from demo theme #}
{% set items = menu.items.toNested %}
<script> 
    $('li.dropdown').hover(function() {
      $(this).find('.dropdown-menu').stop(true, true).delay(0).fadeIn(500);
    }, function() {
      $(this).find('.dropdown-menu').stop(true, true).delay(0).fadeOut(500);
    });
</script>
{% for level1 in items %}
    {% set hasChildren = level1.children|length %}
    {% set isActive = level1.code|slug in this.page.meta_title|slug %}
    
    {% if level1.is_hidden == 1 %}
    {% else %}
        <li class="nav-item {{ hasChildren ? ' dropdown' }}">
            <a class="nav-link {{ isActive ? 'active' }} {{ hasChildren ? 'dropdown-toggle' }}"  href="{{ level1.reference|link }}"{% if hasChildren %} role="button" data-bs-toggle="dropdown" aria-expanded="false"{% endif %}>{{ level1.title }}</a>
            
            {% if hasChildren %} {# HAS CHILDREN IN LEVEL1 #}
                <ul class="dropdown-menu">
                    {% for level2 in level1.children %}
                        {% if level2.is_hidden == 1 %}
                        {% else %}
                            <li><a class="dropdown-item" href="{{ level2.reference|link }}">{{ level2.title }}</a></li>
                        {% endif %}
                    {% endfor %} {# END LOOP LEVEL2 #}
                </ul>
            {% endif %} {# END HASCHILDREN IN LEVEL1 #}
        </li>
    {% endif %} {# CHECK IF LEVEL1 IS_HIDDEN #}
{% endfor %} {# END LOOP LEVEL1 #}

    SEO:

This is possible with the following strategy:

  1. Add a “code” field to each menu item, or use the unique slug

  2. Use the resources component to set an “activeMenu” variable for each CMS page

[resources]
activeMenu = "active-slug"

Then in Twig

{{ if activeMenu == item.slug ? 'active' }}

You can also introduce activeSubMenu for submenu items.

I hope this helps.
