The Textarea controls allow you to add a simple, multi-line text input.

Example

new \Kirki\Field\Textarea(
	[
		'settings'    => 'textarea_setting',
		'label'       => esc_html__( 'Textarea Control', 'kirki' ),
		'section'     => 'section_id',
		'default'     => esc_html__( 'This is a default value', 'kirki' ),
	]
);
