请帮我在这。

推荐答案

让您的数组作为一个列表：

Get your arrays as a list:

$this->set('teams', $this->TeamMembers->find('list'));

然后在表格可以设置的选项：

Then in the form you can set the options:

$this->Form->input('team_member', array('options' => $teams));

更新
您将需要的JavaScript / CSS来操作，才能做到你所要求的选择字段。无在目前没有设置将让你在寻找一个答案的标签。这不能与普通的HTML / PHP code来完成。

UPDATE You will require javascript / css to manipulate the select field in order to do what you are asking. None of the tags you currently have set will get an answer you are looking for. This cannot be done with regular HTML / PHP code.
