Bagaimana cara menampilkan data by category di laravel livewire

Selamat siang, bagaimana ya cara menampilkan data post by category di laravel livewire ? disini saya ingin mencoba menampilkan data post by category dengan cara seperti di bawah ini namun masih belum berjalan:

web.php
Route::get('category/{category:slug}',[FrontController::class, 'category'])->name('category');

FrontController.php
public $search;
    public function category(Category $category)
    {
        $categories = Category::all();
        $general = General::find(1);
        $locale = App::currentLocale();

        $category_id = $category->id;
        $search = request("search");

        $posts = Post::where([
            ['lang',$locale],
            ['category_id',$category_id],
            ['status','PUBLISH'],
        ])->latest()->paginate(12);

        if ($this->search !== null) {
            $posts = Post::where([
                ['title','like', '%' . $this->search . '%'],
                ['lang',$locale],
                ['category_id',$category_id],
                ['status','PUBLISH'],
            ])->latest()->paginate(12);
        }

        // dd($category_id);
        $tags = Tag::all();
        $top        = Post::where('status','PUBLISH')->orderBy('views','desc')->limit(5)->get();
        return view ('front.category',compact('categories','category_id','general','locale','posts','tags','top'));
    }

</div>
Kalau saya dd($category_id); di FrontController.php muncul id dari kategori tersebut, tapi kalau saya coba dd di livewire\CategoryIndex.php muncul null. gimana ya cara yang benar untuk menampilkan post by category ? terimakasih

Solved. issue ini sudah teratasi dengan

di livewire\CategoryIndex.php
<?php

namespace App\Http\Livewire;

use Livewire\Component;
use App\Models\{Category, Post};
use Illuminate\Support\Facades\App;

class CategoryIndex extends Component
{
    public $limitPerPage = 10;

    public $search;

    public $categoryId;

    protected $listeners = [
        'category-index' => 'CategoryIndex'
    ];

    protected $updatesQueryString = [
        ['search' => ['except' => '']],
    ];
   
    public function CategoryIndex()
    {
        $this->limitPerPage = $this->limitPerPage + 6;
    }

    public function render()

        }
        
        $this->emit('postStore');

        // dd($this->categoryId);

        return view('livewire.category-index', ['posts' => $posts]);
    }
}


di category.blade.php melakukan perubahan
<input type="hidden" name="tag_id" value="{{ $tag_id }}">    
<livewire:tag-index :tagId="$tag_id" />

Apakah kamu sudah mengoper parameter dari blade file ke component livewirenya?

//contoh oper variable post ke livewire dari blade
<livewire:show-post :post="$post"> 

//Contoh menerima variable post di component
class ShowPost extends Component
{
    public $title;
    public $content;

    public function mount($post)
    {
        $this->title = $post->title;
        $this->content = $post->content;
    }

    ...
}

}


di category.blade.php melakukan perubahan
<input type="hidden" name="tag_id" value="{{ $tag_id }}">    
<livewire:tag-index :tagId="$tag_id" />
