和组件 Main.php ，

<?php

namespace App\Http\Livewire\Admin\Category;

use App\Models\Admin\Category;
use Livewire\Component;
use Livewire\WithPagination;

class Main extends Component
{
    use WithPagination;

    protected $categories;
    public $showCreateForm = false;
    public $showEditForm = false;
    public function render()
    {
        $categories = Category::orderBy('id','desc')->paginate(12);
        return view('livewire.admin.category.main',[
            'categories' => $categories,
        ]) ->layout('layouts.admin');
    }

    public function createCategory()
    {
         $this->showCreateForm = !$this->showCreateForm;
    }
    public function update_Category($id)
    {


         $categories = Category::whereId($id);
         if ($categories) {
            $this->emit('getCategoryid' , $categories);
            $this->showEditForm = !$this->showEditForm;
            $this->showCreateForm = false;
         }
    }
    public function delete_Category($id)
    {
         $this->showCreateForm = !$this->showCreateForm;
    }
}

我尝试了 iRestWeb Answer，我认为它是正确的答案，但我什至不明白它 100% 与 javascript 相关的事情发生了，这不是我的专业领域，所以这是我的完整代码，希望有人能理解，如果我的代码混乱，再次抱歉辛苦你了，谢谢你。

解决方案

所有的 HTML 代码都应该用 single 覆盖，<div>.然后它就可以工作了。
