+#### Usage in blocks schema
+
+Used in along with `InlineForm`, one can instantiate and configure it using the widget props like this:
+
+```js
+{
+  title: 'Item',
+  fieldsets: [
+    {
+      id: 'default',
+      title: 'Default',
+      fields: ['href'],
+    },
+  ],
+  properties: {
+    href: {
+      title: 'title',
+      widget: 'object_browser',
+      mode: 'link',
+      selectedItemAttrs: ['Title', 'Description'],
+    },
+}
+```
+
+#### selectedItemAttrs
+
+You can select the attributes from the object (coming from the metadata brain from
+@search endpoint used in the browser) using the `selectedItemAttrs` prop as shown in the
+last example.
+
 #### ObjectBrowserWidgetMode()
 
 Returns the component widget with _mode_ passed as argument.
