The Feed-backed drop-down option works exactly like the Enable feed browser option, but displays the results in a drop-down instead of in the feed browser window:

Example: Link Image Field to Graphic Hub Folder

In this example we set up a link from an image field in the template to a Graphic Hub folder, and present the result in a sorted drop-down. 

  • For the image field in the template, choose Feed-backed drop-down from Data entry.

  • The Feed URL should point to a Graphic Hub folder, and we added a search term parameter to display only images. The URL is part of the Graphic Hub REST API.
    To quickly build a valid URL to a folder in Graphic Hub, follow these steps:

    • The {$GH} environment variable can be used to build the base URL part. This variable resolves to the configured graphic hub on Pilot Data Server (for example, http://gh-host:19398/).

    • Add the /files/ part of the path.

    • Add the UUID of the folder to the URL. This value can be copied from Viz Artist when browsing in Asset view:

    • Add the ?/term=IMAGE to the URL.

  • In the Select from feed item drop-down, select Entry. This makes sure the complete Atom entry is put into the field, making it playable for the Viz Engine.

  • Click Sort by title to make the entries sorted.

  • The result should be a sorted drop-down with the images in the Graphic Hub folder.
