How to use states for inline entities?

function my_module_form_alter(&$form, FormStateInterface $form_state, $form_id) { $form['my_field_a']['#states'] = array( 'invisible' => array( ':input[name="my_field_b"]' => array('value' => 'some_value'), ), ); }

function my_module_inline_entity_form_entity_form_alter(&$entity_form, FormStateInterface $form_state) { $entity_form['my_field_a']['#states'] = array( 'invisible' => array( ':input[name="my_field_b"]' => array('value' => 'some_value'), ), ); }

@stijndmd yes, this is possible. Here's an example where a field within a paragraph IEF is displayed based on the value of a field from the parent form. Your specific form structure will vary, so have a look at the parents array and the name of the controlling field.

function mymodule_inline_entity_form_entity_form_alter(&$entity_form, &$form_state) {
  if ($entity_form['#entity_type'] === 'paragraph' && $entity_form['#bundle'] === 'my_paragraph_type') {
    if ($entity_form['#array_parents'][0] === 'field_my_parent_field' && is_numeric($entity_form['#array_parents'][2])) {
      $parent_field_delta = $entity_form['#array_parents'][2];
      $entity_form['my_conditional_field']['widget']['value']['#states'] = [
        'visible' => [
          ":input[name=\"field_my_parent_field[$parent_field_delta][subform][my_controlling_field][value]\"]" => ['checked' => TRUE]
        ],
      ];
    }
  }
}
