Genius I'll give this a go later. Spent an hour trying to mod the knp_menu.twig last night to accomplish this but didn't get too far, hah.

IMHO the "label" (as described http://symfony.com/doc/master/bundles/KnpMenuBundle/i18n.html)
should be:

{%- block label %}
{{ item.label|trans(
    item.getExtra('translation_params', {}),
    item.getExtra('translation_domain', 'messages')
) }}
{%- endblock %}

Thanks for this (and Niels for the original post). Here is an updated RequestVoter passing the RequestStack instead of the whole container:

<?php

namespace Acme\HelloBundle\Menu;

use Knp\Menu\ItemInterface;
use Knp\Menu\Matcher\Voter\VoterInterface;
use Symfony\Component\HttpFoundation\RequestStack;

class RequestVoter implements VoterInterface
{
    private $requestStack;

    public function __construct(RequestStack $requestStack)
    {
        $this->requestStack = $requestStack;
    }

    public function matchItem(ItemInterface $item)
    {
        $request = $this->requestStack->getCurrentRequest();

        if ($item->getUri() === $request->getRequestUri()) {
            // URL's completely match
            return true;
        } else if ($item->getUri() !== $request->getBaseUrl() . '/' 
            && substr($request->getRequestUri(), 0, strlen($item->getUri())) === $item->getUri()) {
            // URL isn't just "/" and the first part of the URL match
            return true;
        }

        return null;
    }
}

And the updated service file:

services:
    acme.hello.menu.voter.request:
        class: Acme\HelloBundle\Menu\RequestVoter
        arguments: [ @request_stack ]
        tags:
            - { name: knp_menu.voter }

Why should I add the RequestVoter? Everything works fine without it?
I don't understand the reason to add the RequestVoter.

Thanks @nateevans

Just a little correction, the span element in knp_menu.html.twig is closed before the macros argument

<span>{{ macros.attributes(item.labelAttributes) }}>

it should be:

<span {{ macros.attributes(item.labelAttributes) }}>

Great work!

Hi. New here.
I'm trying to use this example.
But I get an error that says "Unable to find template "AppBundle:Menu:knp_menu.html.twig""
I create the knp_menu.html.twig inside the views folder in the App/Resources folder.

This is the part I dont understand:
{{ knp_menu_render('AppBundle:MenuBuilder:mainMenu', {'currentClass': 'active', 'template': 'AppBundle:Menu:knp_menu.html.twig'}) }}

Does the second parameter with the twig has to be under a menu folder inside the AppBundle???
Thanks in advance

Hi there,

Thank you for these snippets. I have created a derivative of it to let it work with KeenThemes Metronic Admin Template 4 (sidebar): https://gist.github.com/woutsanders/79b3551f2c4f07ddaab3c74fa9aba132
I'm sure some stuff could be done a bit more efficient, but it's my first experience with this bundle and thus things could be a bit messy here and there.

I couldn't have done it without this gist (as mentioned in my gist).

Again, thank you for the work Niels! And Nate for posting it here :-)

I fixed several bugs in the template (and made some corresponding modification in builder):

just curious, but the extends line in knp_menu.html.twig refers back to itself so this ends up in an endless loop. Am I missing something? I put the twig file in my Resources/views folder however I feel like that's probably not where I am supposed to put it...

Bootstrap 4

Just be aware that dropdowns my bootstrap 4, is not officially supported

            ]
        );

        $dropdown = $menu->addChild(
            'Hello Me',
            [
                'attributes' => [
                    'dropdown' => true,
                ],

        $dropdown->addChild(
