Binding Collections to a Form

The act of adding an IDO collection to a form automatically binds the collection to the form. Most forms have IDO collections bound to them at the time the form is created.

If a form has no bound IDO collection, the first IDO collection that you add automatically becomes the primary collection.  

You can also add other IDO collections to a form that is already bound to a primary collection. These secondary collections can be used as subcollections.

Once added, you can remove any secondary collection from a form. You cannot remove a primary collection.

When working with forms and collections, you can:

• Add an IDO collection to a form
• Edit IDO collection specifications
• Remove a secondary IDO collection from a form
