Stacked widget

The Stacked widget (custom_stacked) is the default widget. It displays each subfield in a vertical stack, exactly like standard Drupal fields. This layout is ideal when you want full-width editing controls and maximum clarity for complex or nested data.

Settings

These settings control the outer container, summary label behavior and individual subfield widgets.

Setting	Label	Description	Default
wrapper	Wrapper	The wrapping element (div, fieldset, or details)	details
label_value	Label value	Optional subfield value to serve as label in details summary
label_limit	Label limit	Maximum number of characters to display in the label for details summary	60
label_prefix	Label prefix	Prefix shown before the label in the details summary when label_value is empty	Item
open	Show open by default	Displays details elements as expanded by default	TRUE
auto_collapse	Auto-collapse	Automatically collapses other open details elements when a new one is selected	FALSE
fields	Field settings	Widget settings for each individual subfield	Default widget plugin + settings

Field settings (per subfield)

The Custom Field module includes a powerful plugin system that lets you fully customize each subfield.

For every subfield you can:

• Choose its own widget (just like regular Drupal fields)
• Override the Label
• Configure all widget-specific settings

These per-subfield options are managed under the Field settings section for each field widget configuration.
