Open the Feed you need, click "Fields" in the left menu, and add a new Reference field.

Fill in the title and select the Feed you want to link in the "Feed" field. Then save the changes.

Open a post and find the new field in the post card. In the dropdown menu, all the posts from the Feed you selected for linking will be displayed. Select the required post from the list. You can then display its fields in the tiles of the current Feed or in a post page template in Zero Block.

Open the page where you created post tiles in Zero Block. Open the Block Editor and add a new element, such as Text.

Move the element to the "Post" group. Then add any other elements you want to link to the fields from the linked Feed.

For example, you can add an image and two text elements. The image will display the author's photo, while the text elements will display their name and position. For convenience and visual understanding, you can style and group the elements in advance.

Select an element and click the Link to Feed icon in the settings panel on the right. In the context menu, select the reference field. Hover over it to view all available fields from the linked Feed. Click the field you need to link it to the element.

Repeat these steps for each element you want to link to fields from another Feed.

In this example, we linked the image, name, position, and color. The screenshot below shows how these fields appear in the "Authors" Feed.

Using this feature, you can link CMS Feeds to each other and display the data from one Feed in the tiles of another.

Reference fields can also be displayed in a post page template.

To do this, open the Zero Block that contains the post fields. Click the plus icon and, in "Post Template," select the required field from the linked field menu.

The added fields will be linked to the Feed automatically.

You can also add any element to Zero Block and link it to a reference field manually. To do this, select the element, click the Link to Feed icon, and select the required linked field from the list.

Reference fields can also be displayed in any block from the "Feeds and CMS" category.

To do this, open the Block Library, go to the "Feeds and CMS" category, and add the required block to the page. Then click "Content" to edit it.

Go to the "Cards" tab and click "Add new item.

In the context menu, hover over the reference field you previously added to the Feed. A submenu with fields from the linked Feed will open. Select the field you need.

Select a style for the added field. For example, in this case, a reference text field is added and the "Tag" style is selected for it. The field will then be displayed in the posts' cards.
