This Contao CMS extension provides an input type group that allows
repeatable groups of fields in the backend. The resulting data is either
stored as a serialized array or in a custom entity relationship (ORM).
The group element widgets are still 'first class citizens' of the respective DCA. Only their definition will be made on the fly. This way we're not messing with the act of rendering and state of the displayed child widgets. As a result, adding new elements via the plus button will submit the current DCA form to add the new element.
Visual reordering of elements is done via the CSS order property. This way
iframes can be kept alive (the DOM won't change) which is especially helpful
when dealing with components like the tinyMCE rich text editor.

Just give me an example, ok?
$GLOBALS['TL_DCA']['tl_content']['fields']['my_group'] = [
'inputType' => 'group',
'palette' => ['amount', 'singleSRC', 'text'],
'fields' => [
'amount' => [ // additional field, defined inline
'inputType' => 'text',
'eval' => ['tl_class' => 'w50'],
],
'&singleSRC' => [ // let's change some properties of the existing field
'eval' => ['mandatory' => false],
]
],
// force at least 1, at max 5 elements
'min' => 1,
'max' => 5,
// disable ordering (on by default)
'order' => false,
// store serialized into a blob (default storage backend)
'sql' => [
'type' => 'blob',
'length' => \Doctrine\DBAL\Platforms\MySqlPlatform::LENGTH_LIMIT_BLOB,
'notnull' => false,
],
];
