Introducing the feature you've been all waiting since you tried Reference Field Type – ability to add multiple items from referenced collection.
Be aware that if you decide to update your current Reference field type to allow multiple items, your previously added items would not be preserved, so make sure you backup your data or start with creating a new field.
There're also some changes in how you should connect your data when working with Multiple Item Reference field in Editor. Unlike Reference field type in Single Item mode, you won't be able to connect this field type directly to components. Instead, you need to rely on Dataset. Whenever you want to show Movies and their Actors, just add 2 datasets – one for movies and one for actors – and then apply a Filter by Dataset.
Might sound confusing at first, but once you go over this article, you'll be an expert: https://support.wix.com/en/article/working-with-multiple-item-reference-fields.
Also, some more details of how Reference field in this new Multiple Item mode works can be found here: https://support.wix.com/en/article/about-referencing-multiple-items-in-one-reference-field.
Some multiple item reference API:
hasSome() (aka includes some of)
Last but not least, we would really appreciate if you give us some feedback on this feature by filling in this anonymous 4-question form.
