Description:

This key defines the background color of the gallery area on Cards in the Collection browser, Structures, and Snippets.

The value can be an array or a single value, and reference a key, template, or text string. When multiple entries are provided, CloudCannon will use them in order as fallback options.

Color values can be hex codes (e.g., #ff0000), CSS color names, or reference a data key that contains a color value.

Array Preview EntryArray<Preview Entry>#

This key represents an array of preview entries for displaying data on Cards in the Collection browser, Structures, and Snippets.

The value is an array of preview entry objects, strings, or false values. Each preview entry object can contain a key, template, or text property. When multiple entries are provided, CloudCannon will use them in order as fallback options.

In this example, we have configured an array of preview entries with an array of values to provide fallback options. CloudCannon will use the value of title first, then the {name} template, and finally fall back to the static text value.

Raw Text Preview Entrystring#

This key represents a raw text preview entry type for displaying static text on Cards in the Collection browser, Structures, and Snippets.

The value is a string that specifies static text to display in card previews. This is equivalent to using { text: "..." } but in a simpler format.

This key represents a preview entry that disables the preview display for a specific field on Cards in the Collection browser, Structures, and Snippets.

The value must be false. Setting a preview entry to false will hide that preview element.
