How to create repeatable blocks (not custom fields)

What have you tried thus far in terms of the individual fields? What are you experiencing vs what are you expecting to experience?

If you could provide all of the metabox code you have at the moment, that’d be a big help.

Thanks for the reply Michael.

Please find the code that I need to make repeatable – into a group.

Thanks again, in advance!

$panel9_box = new_cmb2_box( array(
	'id'            => $prefix . 'panel9_box',
	'title'         => __( 'Industry Table 5', 'cmb2' ),
	'object_types'  => array( 'page', ),
	'show_on'      => array( 'id' => array( 1741, ) ),
	'priority'      => 'high',
	'repeatable' => true,
));

$panel9_box->add_field( array(
		'name'    => __( 'Table Heading', 'cmb2' ),
		'id'    => 'panel9_indheading',
		'type'    => 'text',
));

$panel9_box->add_field( array(
		'name'    => __( 'Table Content', 'cmb2' ),
		'id'      => 'panel9_indcontent',
		'type'    => 'wysiwyg',
));

Having some minor issues with regards to the wysiwyg field, but something like the following should get you pretty close:

$panel9_box = new_cmb2_box( array(
	'id'           => $prefix . 'panel9_box',
	'title'        => __( 'Industry Table 5', 'cmb2' ),
	'object_types' => array( 'page', ),
	'priority'     => 'high',
	'repeatable'   => true,
) );

$group_field_id = $panel9_box->add_field( array(
	'id'          => $prefix . 'demo',
	'type'        => 'group',
	'description' => esc_html__( 'Generates reusable form entries', 'cmb2' ),
	'options'     => array(
		'group_title'   => esc_html__( 'Entry {#}', 'cmb2' ), // {#} gets replaced by row number
		'add_button'    => esc_html__( 'Add Another Entry', 'cmb2' ),
		'remove_button' => esc_html__( 'Remove Entry', 'cmb2' ),
		'sortable'      => true, // beta
		// 'closed'     => true, // true to have the groups closed by default
	),
) );

$panel9_box->add_group_field( $group_field_id, array(
	'name' => __( 'Table Heading', 'cmb2' ),
	'id'   => 'panel9_indheading',
	'type' => 'text',
	// 'repeatable' => true, // Repeatable fields are supported w/in repeatable groups (for most types)
) );

$panel9_box->add_group_field( $group_field_id, array(
	'name' => __( 'Table Content', 'cmb2' ),
	'id'   => 'panel9_indcontent',
	'type' => 'wysiwyg',
) );

In the extra instances, the WYSIWYG field isn’t working quite right, not sure why at the moment

From the 2.2.3 release:
Make wysiwyg editors work in the repeatable groups context. A standard repeatable (non-group) wysiwyg field is not supported (but will possibly be included in a future update). Props @johnsonpaul1014 (#26, #99, #260, #264, #356, #431, #462, #657, #693).
