 ### Modal view
 
+#### By route
+
 By default the modals are loaded automatically by using `entity` in `on_the_fly` of the field definition, e.g. resulting in `backpack_url($field['on_the_fly']['entity']).'/ajax/create'` for the create modal.
 
 You can overwrite this behavior for all modals by setting an attribute:
 
 ```
 'on_the_fly' => [
     'entity' => 'entity',
-    'create_modal' => 'route/to/modal/html',
-    'edit_modal' => 'route/to/modal/html',
-    'delete_modal' => 'route/to/modal/html',
+    'create_modal'  => 'route/to/modal/html',
+    'edit_modal'    => 'route/to/modal/html',
+    'delete_modal'  => 'route/to/modal/html',
 ]
 ```
 
 > Please be aware that by using this attributes you will be completely responsible for the content of the modal! The defined request has to provide valid HTML which is then filled in `<div class="modal-content"></div>`
 
+#### By view
+
+Instead of defining a route you can also use a custom view by:
+
+```
+'on_the_fly' => [
+    'entity' => 'entity',
+    'create_modal_view' => 'view.to.create.modal',
+    'edit_modal_view'   => 'view.to.edit.modal',
+    'delete_modal_view' => 'view.to.delete.modal',
+]
+```

 ### Search logic
 
 The "instant field" triggers the `ajaxIndex()` of the `EntityCrudController` where the field is defined and uses the fields `model` and `attribute` parameters to perform the search on the foreign model.

+### Passing current field values to foreign `EntityCrudController`
+
+Sometimes you will need current values to be used for the creation of an foreign entity. You may define `serialize` with the IDs of the fields you need in the store request:
+
+```
+'on_the_fly' => [
+    'serialize' => ['type_id', 'name'],
+]
+```
+
+So the current values of `type_id` and `name` will be available in the `$request` of the `ajaxStore` method of your foreign `EntityCrudController` (you will have to overwrite it).
