Allow collapsing optional fields

Recommended Approach

// Suggested data structure for field configuration
$field_definition->setSetting('table_display', [
  'collapsible' => TRUE,
  'default_state' => 'collapsed', // or 'expanded'
]);

it already exists you convert to bootstrap 5 table or datatable it is available

Nice, thank you @lazzyvn - we'll have a deeper look at that and update the status here accordingly!

Maybe a screenshot or description of the feature on the module page would be nice?
