Apply "currentClass" in link in item

[guillaumecardon]

Hello,

Using this Twig syntax : {{ knp_menu_render('main', {'currentClass' : 'active'}) }}, the css class "active" is applied to "li" tag.
However, is there an option or specific syntax to apply the currentClass on link inside the "li" tag ?

Actual result :
<li class="nav-item active"><a href="/user/" class="nav-link">Users</a></li>

Expected result :
<li class="nav-item active"><a href="/user/" class="nav-link active">Users</a></li>
or
<li class="nav-item"><a href="/user/" class="nav-link active">Users</a></li>

Thanks

You can use a custom template for that.

Ok, after many tests to understand the logic, this is a solution :

{% block linkElement %}
    {% import _self as knp_menu %}
    {%- set classes = item.linkAttribute('class') is not empty ? [item.linkAttribute('class')] : [] %}
    {%- if matcher.isCurrent(item) %}
        {%- set classes = classes|merge([options.currentClass]) %}
    {%- endif %}
    {%- set attributes = item.linkAttributes %}
    {%- if classes is not empty %}
        {%- set attributes = attributes|merge({'class': classes|join(' ')}) %}
    {%- endif %}
    <a href="{{ item.uri }}"{{ knp_menu.attributes(attributes) }}>
        {{ block('label') }}
    </a>
{% endblock %}
