Multi-reference field

 

A multi-reference field is just like a reference field, except it allows you to reference more than one item from another Collection and then present these items in a Collection List on a Collection Page. This is great for tagging systems and other instances where you want to connect one item to many others.

Common uses
  • Blog post Collection referencing multiple authors from an Authors Collection
  • Projects Collection referencing multiple tags in a Tags Collection
In this lesson
  • Creating a multi-reference field
  • Referencing items
  • Using the multi-reference field in your design

Creating a multi-reference field

The beauty of the reference and multi-reference fields is that whenever you edit an item that’s being referenced, the new content will automatically update everywhere it’s referenced.

So, for example, if I updated a related blog post's name, every reference to that blog post will update automatically.

To add a multi-reference field to a Collection, click New Field and then choose the multi-reference field.

Choose a Collection to reference

In multi-reference field’s settings, you can choose which Collection you want the current Collection to reference.

 

Other field settings

You can also specify the name, help text, and whether the field is required to publish.

Need to know
You get a limited number of references per Collection. Check out the features list to learn more.

Referencing items

Once you've added a multi-reference field to a Collection, you can go into your Collection items and start adding references. You can choose multiple items from the Collection you chose in the reference field settings.

 

Using the multi-reference field in your design

To use multi-reference fields in your designs, connect a Collection List to this field in a Collection Page that has that field. You can then connect to elements and styles inside this Collection List.

Connecting to a Collection List

In this example we have a Blog Posts Collection with a multi-reference field that’s referencing the Tags Collection. Drop a Collection list onto the Blog Post Collection page, and connect it to the Tags multi-reference field.

Must know
Make sure you connect to the multi-reference field and not the actual Collection that is referenced. If you connect to the actual collection, that will pull all the Collection items in that collection instead of only the referenced ones.
Good to know
There’s no filtering options for this Collection list because it automatically shows the referenced items for that page.
Also, there’s no sorting options for a Collection list that's connected to a multi-reference field. That's because it automatically shows the referenced items in the order that you've selected them within the multi-reference field.
Must know
At the moment, you can show multi-reference field values only on a Collection page, and not within a Collection list. Support for nested Collection lists is planned. Vote for and subscribe to status updates of this feature request.

Connecting elements and styles

When you add an element to this Collection List, you can pull the content for that element from any of the referenced Collection’s fields. For example, you can use a tag’s name in a heading element and the tag’s icon in an image element.

 

In this clip, we show you how you can pull the values of a number of fields from a Contributors Collection right into a Blog Post.

Filtering a Collection list using the multi-reference field

You can filter a Collection list using the Multi-reference field only on the referenced Collection page. For example, on the Tags Collection Page, you can show all Blog Posts that reference that Tag. To do this:

  1. Add a Collection list and connect it to the Blog Posts Collection
  2. Create a Collection list filter with the Tags (multi-reference), contains, Current Tag.

Setting conditional visibility using the multi-reference field

You can set conditional visibility to show or hide individual elements in a collection list or on a collection page using the multi-reference field.

Where can you use this type of conditions?

This type of condition can only be created within a collection list that's connected to the collection that has the multi-reference field or on the collection template page of this collection.

For example, if you have a collection called “Blog posts” that has a multi-reference field linked to a collection called “Authors”, you can add conditions based on the reference field “Authors” in any collection list that is connected to the “Blog posts” collection as well as on the “Blog posts” template page.

What kind of conditions can you set?

You can add the following conditions based on the multi-reference field:

  • when the multi-reference field is set or is not set
  • When the multi-reference field contains or doesn’t contain a specific value
Example — condition when a multi-referenced field is set

Let’s say we want to add an Author’s section under each blog post on the Blog post template page. We can do that by adding a collection list and connecting it to the Authors multi-reference field.

Now, what if we add a heading to this section? We want the heading to appear only when there are authors set in the multi-reference field. So we need to set a condition on the heading like this:

  1. Select the heading
  2. Add a condition under the conditional visibility section in the settings panel
  3. Select your multi-reference field, Authors (multi-reference), in the first dropdown
  4. Choose Is set in the second dropdown
  5. Save
