How to show hide resources based on roles/permission while using advance navigation customization

[valpuia]

For roles and permission I used Shield plugin.

And for language switch Language Switch plugin.

If I create the side bar navigation like normal, The position changed based on language change, then I used Advance Navigation Customization. The position changed is resolved means they stay on their position after language changed.

But I got another problem, the sidebar navigation always show if the user cannot access the particular resource also.

How to make the sidebar navigation based on the roles, like normal navigation (in normal navigation, they show/hide based on their roles and permission as expected)

You should check ::shouldRegisterNavigation() on resources before registering them in the navigation

I got Method App\Filament\Resources\PostResource::shouldRegisterNavigation does not exist. can you briefly explain how to use, you can see my code below inside 'AppServiceProvider'

use App\Filament\Resources\PostResource;
use Filament\Facades\Filament;
use Filament\Navigation\NavigationBuilder;
use Filament\Navigation\NavigationGroup;

Filament::navigation(function (NavigationBuilder $builder): NavigationBuilder {
    $builder->items([
        ...Dashboard::getNavigationItems(),
    ]);

    $builder->groups([
        NavigationGroup::make(__('message.post.management'))
            ->items([
                // ...PostResource::getNavigationItems(), // previous registration (cannot hide/show base on role-permission)
                ...PostResource::shouldRegisterNavigation(), // throw above error here
            ]),
    ]);

    return $builder;
});

Ah I just realised that method is protected in v2. Try this instead:

use App\Filament\Resources\PostResource;
use Filament\Facades\Filament;
use Filament\Navigation\NavigationBuilder;
use Filament\Navigation\NavigationGroup;

Filament::navigation(function (NavigationBuilder $builder): NavigationBuilder {
    $builder->items([
        ...Dashboard::getNavigationItems(),
    ]);

    $builder->groups([
        NavigationGroup::make(__('message.post.management'))
            ->items([
                ...(PostResource::canViewAny() ? PostResource::getNavigationItems() : []),
            ]),
    ]);

    return $builder;
});
