Visualforce pages can pass parameters to components via attributes. A component declares the attributes that it is able to accept, including information about the type and whether the attribute is mandatory or optional. Attributes can be used directly in the component or assigned to properties in the component's controller.
In this recipe we will create a Visualforce page that provides contact edit capability. The page utilizes a custom component that allows the name fields of the contact, Salutation, First Name, and Last Name, to be edited in a three-column page block section. The contact record is passed from the page to the component as an attribute, allowing the component to be re-used in any page that allows editing of contacts.
