checkboxes

The checkboxes type is a useful type that allows you to select multiple values in the admin panel from a list of choices. These choices can be either defined in the model or dynamically loaded from the tree of pages.

The configuration of the type is a bit more involved because of it's flexibility. The following options exist:

• source: if provided it should be an expression that evaluates to an iterable of records. The variable record thereby points to the current record.
• choices: instead of source this can be provided in which case it is a comma separated list of values.
• choice_labels: when choices is given, this is used as labels to display it in the UI. It's a comma separated list of values.
• item_key: an template format expression to convert a source item into the value that is stored. This defaults to {{ this._id }} which means that the ID of the selected record is stored.
• item_label: similar to item_key but for the UI part. This has no default which means that the record's configured title will be used as label.

In the contents file the values are stored as comma separated list.
