You can use the Repeater meta field to combine multiple contents of the same type. It helps to avoid plural separate meta fields. With the Repeater meta field, you can group and collapse contents for your convenience.

For instance: 

• A rent house with a description of facilities per floor; 
• Tour plans where each repeater item is a day of the program of the tour;
• Team Member experience etc.

Field Settings

Decide where you need the repeater field. You can create it for posts, custom content type items, users, options pages, and products. 

Build it by editing custom post type, custom content type, and options page, or you can create a custom meta box for users, products, etc. 

So let’s start with the main settings:

• Label — the label you see in the back end of the post, user, etc., side by your field. It can consist of different characters;

• Name/ID —  field name/key which will be stored in the database. It should contain only Latin letters, lower case, numbers, `-` or `_` as symbols;

• Object type — here, “Field” should be selected;

• Field type — the list of available fields. Pick the “Repeater” option;

Press the “New Repeater Field” button to add repeater item fields. Here, you can read about meta field types.

Rules for the Label and Name are the same. Now, let’s look at the following repeater settings.

• Collapsed — toggle this option to collapse repeater item fields on the page load;

• Title Field — pick a repeater item field to show as a repeater item title (the one you created as a nested meta field);

• Description — add a small description for your convenience or for other users who will have access to the website’s back end;

• Is Required — switcher that defines whether its field is required to create/update post/user/item; 

• Show in Rest API — toggle to be activated to make this field visible with WordPress Rest API and available to edit.
• Conditional Logic — set meta field display rules.

Now click the “Save Changes” button and navigate to the source of your Repeater field. In the described case, it’s User experience. Click the “New Item” button to see your fields and create as many items as you need.
