+choice_translation_parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**type**: ``array`` **default**: ``[]``
+
+The choice values are translated before displaying it, so it can contain
+:ref:`translation placeholders <component-translation-placeholders>`.
+This option defines the values used to replace those placeholders.
+
+Given this translation message:
+
+.. code-block:: yaml
+
+    # translations/messages.en.yaml
+    form.order.yes: 'I confirm my order to the company %company%'
+    form.order.no: 'I cancel my order to the company %company%'
+
+You can specify the placeholder values as follows::
+
+    $builder->add('id', null, [
+        'choice' => [
+            'form.order.yes' => true,
+            'form.order.no' => false,
+        ],
+        'choice_translation_parameters' => [
+            '%company%' => 'ACME Inc.',
+        ],
+    ]);
+
+The ``choice_translation_parameters`` option of children fields is merged with
+the same option of their parents, so children can reuse and/or override any of
+the parent placeholders.
