CakePHP make select dropdown

Does anybody know how to select the contents of one take from a different view in cakephp.

I have a take itemgroups that has 2 fields ID and Description. I need to make a down down list in the item add page but I can not find a good way to get all of the values from another table into an array to put into the page.

Below I have also listed my models for each.

array('rule' => 'notEmpty'),'description' => array('rule' => 'notEmpty'));
