所有的HTML代码都应该用一个<div>.覆盖，然后它就可以工作了。

在base.blade.php文件中添加liveWire的css和js，它可以工作：

<head>
...
    @livewireStyles
</head>
<body>
    ...

    @livewireScripts
</body>
</html>

我想这个会对你有帮助

<a href="#" wire:click.prevent="$toggle('showCreateForm')" class="btn btn-success">Add New Category</a>

您不需要:click事件来执行此操作，只需用途：

wire:$toggle('property')

字符串
你不需要使用a标签;你可以简单地使用button标记。所以你的按钮代码看起来像这样：

<button type="button" wire:$toggle='showCreateForm' class="btn btn-success">Add New Category</button>
