19. CollectionView� {{#collection movies}} {{#link "details/{{_key}}" expand-tokens=true}} <li>{{title}}</li> {{/link}} {{/collection}} Also supports filtering
20. Thorax.Layout� layout.setView( ... ) <div class=“container"> {{layout-element}} </div>
21. model lookup� someEvent: function(ev) { var target = $(ev.currentTarget); var model = target.model(); // change model ... }
22. events� var listView = new Thorax.View({ el: "#movies", events: { collection: { reset: function(ev) { // automatic bound } } } }
23. subviews� <div class="header"> {{view header}} </div>
