Filament Collapsible Sub-Navigation

A Filament v3, v4 & v5 plugin that adds a collapsible toggle to sub-navigation sidebars only. Perfect for resource pages with multiple tabs or sections using ->subNavigationPosition(SubNavigationPosition::Start).

Works with both top navigation and sidebar navigation layouts — the plugin specifically targets the sub-navigation sidebar that appears on individual resource pages, not the main panel navigation.

Without Top Navigation (Sidebar Layout): Expanded Sidebar

With Top Navigation: Collapsed Sidebar

Compatibility

Plugin version	Filament	PHP	Laravel
`^1.0`	v3, v4, v5	8.1+	10 / 11 / 12 / 13

Note: This plugin only affects sub-navigation sidebars (the secondary navigation within resource pages), not the main panel sidebar. It works regardless of whether you use top navigation or sidebar navigation for your main panel layout.

Installation

Install the package via composer:

composer require emuniq/filament-collapsible-subnav

That's it! The plugin auto-registers to all panels and works immediately with zero flash.

Optional: Theme Integration

For a slight performance boost, you can integrate the CSS into your Filament theme:

php artisan collapsible-subnav:install
npm run build

This bundles the plugin CSS with your theme, reducing HTTP requests. Not required — the plugin works perfectly without this step.

Features

✅ Zero configuration — Auto-registers to all panels
✅ Collapsible sub-navigation sidebar toggle
✅ Persistent state using cookies (server-side rendered to avoid FOUC)
✅ Works with SPA mode (livewire:navigated re-sync)
✅ Tooltips for collapsed items (native fallback for v4, Tippy for v3)
✅ Responsive — hidden on mobile (<768px)
✅ Smooth transitions
✅ No theme, npm, or build step required

How It Works

The plugin automatically:

Registers itself to all Filament panels on installation
Injects critical CSS in the <head> to prevent flashes on reload
Adds a toggle button to sub-navigation sidebars only (not main panel navigation)
Persists the collapsed/expanded state via the subnav_collapsed cookie
Re-syncs after each Livewire SPA navigation

The plugin detects pages with sub-navigation and only applies to those specific sidebars, leaving your main panel navigation (top or sidebar) untouched.

Manual Registration (Optional)

If you prefer manual control, you can register the plugin explicitly on individual panels:

use Emuniq\FilamentCollapsibleSubnav\CollapsibleSubnavPlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        // ...
        ->plugin(CollapsibleSubnavPlugin::make());
}

Troubleshooting

Cloudflare Rocket Loader strips the early script. The plugin marks its critical inline script with data-cfasync="false" so Rocket Loader skips it. If you still see a flash on reload, check that your CDN or HTML minifier preserves the attribute.

SPA mode (->spa()) leaves the toggle out of sync. Fixed since the SPA re-sync patch — the plugin now listens to livewire:navigated and re-applies state on every navigation.

Tooltips don't appear in Filament v4. Filament v4 doesn't expose Tippy globally; the plugin falls back to the native HTML title attribute so a tooltip always shows on hover.
