Component Link fields
Add a Component link field to a Schema to allow content authors to create a link to a Component. You can also allow an author to add a multimedia Component using this field type.
About this task
You can specify the Schemas upon which the selectable Components must be based, or you can allow the content author to link to any Component.
For example, if you wanted to allow an author to add any kind of link to the Component, you do not need to specify a Component. On the other hand, if you want to ensure that author links to a specific kind of content, you can select an appropriate schema that allows for that content only.
