Add a Related media custom field

You use this field to add an option to attach a media to a content item in the backend and then display the media together with the item on the frontend.

EXAMPLE: You add an image custom field to the News module. Then, you create a news item. You can see the custom field and you can use it to add one or more images to the news item. Then, you must add the image custom field to the widget template of the News widget. When you drop the widget on a page, the website displays news, together with images.

You can add a media field to built-in and dynamic modules, as well as pages. The supported media types are images, videos, and files.

To add a media field to a module or page, perform the following:

1. Perform procedure Create custom fields » Step 1 to Step 5.
2. In Type, select Related media.
3. In What kind of media this field will manage?, select one of the following:
   • Images
   • Videos
   • Documents and other files
4. Click Continue.
5. In Source, select the provider (or destination) where you want to store the related media items.
   You can choose between:
   • The default source for this site
   • Any other provider that is set up
   • All sources for the current site

     IMPORTANT: When working in multisite, unless explicitly configured, your sites have different default providers for content. You can share content between sites but each site stores new content in their default provider. For more information, see Share content providers of modules.
     You can change the provider you select at this step at a later point in time. Keep in mind that when changing providers, the provider the Related media field works with changes dynamically as you switch sites to the default provider for the current site. You can also set the source to be all shared providers. To learn about the implications when changing providers, see Considerations and dependencies.

6. Under Interface widget for uploading or selecting images, select the widget that you want to use in the backend to upload or select an uploaded media file.
   By default, images are uploaded with the Image selector, videos – with the Videos selector, documents and other files – with File selector.

   This label is displayed when you create a content item in the backend.
