 Forms will be submitted asynchronously and in case of errors dynamically extended to show errors belonging to inputs fields, but it is possible to set custom form behavior in success or failure cases. You could transition to another page, follow the redirect from the server as a transition or normal redirect, or emit events to leverage the above mentioned event hub.

 The above code snippet renders initially a paragraph and the current time followed by a button which emits the "update-time" event. The `async` component triggers an asynchronous request when the event is recieved, requesting it's content from the server. The server will respond with only the contents of the `async` components which is then replaced.

 **collection**
 
+With the `collection` component you can display active record model or similar collections and add features like filtering, paginating and ordering with ease. Each of these features requires no page reload to take effect, because the `collection` component leverages a `async` component in combination with the event hub to only reload the effected content of the collection. The `collection` component is a bit more complex as it offers a lot of functionality why we will not explain the rudimentary usage here.
