dynamic navigation item in panel

Hey there,

i tried to create a dynamic navigation items:

public function panel(Panel $panel): Panel
{
    return $panel
    //...
    ->navigationItems($this->getNavigationItems());
}

private function getNavigationItems()
{
    if (\auth()->user()->canAccessPanel(Filament::getPanel('admin'))) {
        return [
            NavigationItem::make(fn () => __('Login as admin'))
                ->url('/admin')
                ->icon('heroicon-o-arrow-right-on-rectangle')
                ->visible(fn () => auth()->user()->canAccessPanel(Filament::getPanel('admin')))
                ->group('Administration')
                ->sort(2),
        ];
    } else {
        return [];
    }
}

public function panel(Panel $panel): Panel
{
    return $panel
    //...
    ->navigationItems($this->getNavigationItems());
}

private function getNavigationItems()
{
    if (\auth()->user()->canAccessPanel(Filament::getPanel('admin'))) {
        return [
            NavigationItem::make(fn () => __('Login as admin'))
                ->url('/admin')
                ->icon('heroicon-o-arrow-right-on-rectangle')
                ->visible(fn () => auth()->user()->canAccessPanel(Filament::getPanel('admin')))
                ->group('Administration')
                ->sort(2),
        ];
    } else {
        return [];
    }
}

public function panel(Panel $panel): Panel
{
    return $panel
    //...
    ->navigationItems($this->getNavigationItems());
}

private function getNavigationItems()
{
    if (\auth()->user()->canAccessPanel(Filament::getPanel('admin'))) {
        return [
            NavigationItem::make(fn () => __('Login as admin'))
                ->url('/admin')
                ->icon('heroicon-o-arrow-right-on-rectangle')
                ->visible(fn () => auth()->user()->canAccessPanel(Filament::getPanel('admin')))
                ->group('Administration')
                ->sort(2),
        ];
    } else {
        return [];
    }
}

public function panel(Panel $panel): Panel
{
    return $panel
    //...
    ->navigationItems($this->getNavigationItems());
}

private function getNavigationItems()
{
    if (\auth()->user()->canAccessPanel(Filament::getPanel('admin'))) {
        return [
            NavigationItem::make(fn () => __('Login as admin'))
                ->url('/admin')
                ->icon('heroicon-o-arrow-right-on-rectangle')
                ->visible(fn () => auth()->user()->canAccessPanel(Filament::getPanel('admin')))
                ->group('Administration')
                ->sort(2),
        ];
    } else {
        return [];
    }
}

The error

Target class [hash] does not exist.

Target class [hash] does not exist.

Target class [hash] does not exist.

Target class [hash] does not exist.

came up and I don't know where to add the Hash-Class? Can someone help me out?
Thank you

found a workaround to hide the group as well, if the user cannot access the panel:

public function panel(Panel $panel): Panel
    {
      return $panel
      // ... 
      ->navigationItems([
                NavigationItem::make(fn () => __('Login as admin'))
                    ->url('/admin')
                    ->icon('heroicon-o-arrow-right-on-rectangle')
                    ->visible(fn () => $this->canAccessAdminPanel())
                    ->sort(2)
                    ->group(fn () => $this->canAccessAdminPanel() ? __('Administration') : ''),
            ]);
    }

private function canAccessAdminPanel()
    {
        return auth()->user()->canAccessPanel(Filament::getPanel('admin'));
    }

public function panel(Panel $panel): Panel
    {
      return $panel
      // ... 
      ->navigationItems([
                NavigationItem::make(fn () => __('Login as admin'))
                    ->url('/admin')
                    ->icon('heroicon-o-arrow-right-on-rectangle')
                    ->visible(fn () => $this->canAccessAdminPanel())
                    ->sort(2)
                    ->group(fn () => $this->canAccessAdminPanel() ? __('Administration') : ''),
            ]);
    }

private function canAccessAdminPanel()
    {
        return auth()->user()->canAccessPanel(Filament::getPanel('admin'));
    }

public function panel(Panel $panel): Panel
    {
      return $panel
      // ... 
      ->navigationItems([
                NavigationItem::make(fn () => __('Login as admin'))
                    ->url('/admin')
                    ->icon('heroicon-o-arrow-right-on-rectangle')
                    ->visible(fn () => $this->canAccessAdminPanel())
                    ->sort(2)
                    ->group(fn () => $this->canAccessAdminPanel() ? __('Administration') : ''),
            ]);
    }

private function canAccessAdminPanel()
    {
        return auth()->user()->canAccessPanel(Filament::getPanel('admin'));
    }

public function panel(Panel $panel): Panel
    {
      return $panel
      // ... 
      ->navigationItems([
                NavigationItem::make(fn () => __('Login as admin'))
                    ->url('/admin')
                    ->icon('heroicon-o-arrow-right-on-rectangle')
                    ->visible(fn () => $this->canAccessAdminPanel())
                    ->sort(2)
                    ->group(fn () => $this->canAccessAdminPanel() ? __('Administration') : ''),
            ]);
    }

private function canAccessAdminPanel()
    {
        return auth()->user()->canAccessPanel(Filament::getPanel('admin'));
    }

This is working right now and I think I can live with that

just for clarify: I didn't use visible or hidden on NavigationItem, because the group will still be shown even if there is no menu item in it.

Can you click the SHARE button at the top of the error page and paste the link?

Thanks! I'm not entirely sure but I think this could be too early in the Laravel "lifecycle" to access the user instance.

Something to try:

return $panel
    // ...
    ->bootUsing(function ($panel) {
        $panel->navigationItems($this->getNavigationItems());
    })

return $panel
    // ...
    ->bootUsing(function ($panel) {
        $panel->navigationItems($this->getNavigationItems());
    })

unfortunately now auth()->user is null
