When a list of reference elements is shown in the drag & drop widget and more than one has the same label value. At first, we can see all of them in the available list (left side) but if we move one of them (elements with the same label) to the selected list (right side) and save it. When we try to edit we can't see the elements with the same label in the available list.
- create a taxonomy vocabulary with terms with the same title (label) value.
- create a taxonomy term (entity reference) in a content with the drag & drop widget.
- move one of the repeat terms from the available entities (left side) to the selected entities (right side).
- save.
- Edit again this content (just one of the repeat terms appears in the selected entities but the others disappear).
Modify the getAvailableOptions method to filter the elements using the id and not the label
protected function getAvailableOptions(FieldItemListInterface $items) {
// We need to check against a flat list of options.
$flat_options = OptGroup::flattenOptions($this->getOptions($items->getEntity()));
$selected_options = $this->getSelectedOptions($items);
$available_options = [];
foreach ($flat_options as $id => $option) {
if (!array_key_exists($id, $selected_options)) {
$available_options[$id] = $option;
}
}
return $available_options;
}
