I need 2 things
1. i need to disallow adding new custom field by typing the new key - i want to show there only few predefined custom keys i want
2. I need a "select" customfield 2 - explanation: i need to define e.g. "the county" for the post. We have 18 counties, so I want to to allow editor to select one of that 18 counties i predefine. It should be also multiselect - so e.g. more counties per one post.
is there any such option/plugin?
