+The options-addon accepts story paramters to set options (as shown below).
+
+```js
+import { storiesOf } from '@storybook/marko';
+import { withKnobs, text, number } from '@storybook/addon-knobs';
+import { withOptions } from '@storybook/addon-options';
+import Hello from '../components/hello/index.marko';
+
+storiesOf('Addons|Knobs/Hello', module)
+  .addDecorator(withOptions)
+  .addDecorator(withKnobs)
+  .addParameters({ options: { addonPanelInRight: true } })
+  .add('Simple', () => {
+    const name = text('Name', 'John Doe');
+    const age = number('Age', 44);
+    return Hello.renderSync({
+      name,
+      age,
+    });
+  });
+```
+
 It is also possible to call `setOptions()` inside individual stories. Note that this will bring impact story render performance significantly.
