从另一个主题创建Wordpress小部件

Question

我正在尝试将此网站顶部的职位搜索功能添加到https://jobify-demos.astoundify.com/classic/我自己构建的WP主题中。

我已经确定这个'搜索英雄地带'是一个需要安装到我的主题中的小部件，然后我想我需要在我自己的主题中创建一个广泛的区域，以便我可以添加它。

我相信这是主题中的小部件：

        $output .= wpautop( $content );
        $output .= '</div>';

        return $output;
    }
}

我试图在函数文件中添加它，但它只会产生错误。

我知道这可能是基本的，但我确定我错过了一些重要的，但我有点卡住了。

我要么想把它作为一个小部件，要么从中删除搜索表单，只需将其添加到我的主页模板页面即可？
