例如，在下面的代码段中，有一些类型用于自定义metabox输入字段，如text和textarea。所以，我想学习其他类型。我在谷歌上也搜索了它。但我不能。例如，我想学习电子邮件类型。

array(
    \'name\' => \'Instagram\',
    \'desc\' => \'You should write Instagram link here\',
    \'id\' => $prefix . \'text-instagram\',
    \'type\' => \'text\',
    \'std\' => \'https://www.instagram.com/britneyspears/?hl=tr\'
),
array(
    \'name\' => \'Additional Post Description while hover thumbnail\',
    \'desc\' => \'The text will shown on post thumbnail via our elementor post widget\',
    \'id\' => $prefix . \'textarea\',
    \'type\' => \'textarea\',
    \'std\' => \'Its amazing story so I dont know where must I start to tell...\'
