 ## Custom Invoker
 
 You can provide a custom invoker using the invoker slot.
-This means it will get the selected value(s) as an input property `.selectedElement`.
+LionSelectRich will give it acces to:
 
-You can use this `selectedElement` to then render the content to your own invoker.
+- the currently selected option via `.selectedElement`
+- LionSelectRich itself, via `.hostElement`
+
+Code of an advanced custom invoker is shown below (this is the code for the
+invoker used in [IntlSelectRich](./examples.md)).
+The invoker is usually added in the invoker slot of the LionSelectRich subclass.
+However, it would also be possible for an application developer to provide the invoker
+by putting it in light dom:
 
 ```html
 <lion-select-rich>
-  <my-invoker-button slot="invoker"></my-invoker-button>
+  <intl-select-invoker slot="invoker"></intl-select-invoker>
   ...
 </lion-select-rich>
 ```
 
-An example of how such a custom invoker class could look like:
-
 ```js
-class MyInvokerButton extends LitElement() {
-  static get properties() {
+import { LionSelectInvoker } from '@lion/select-rich';
