    <p>I just implemented this last night.</p> <p>You can set a new collection <code>comparator</code> and then use the <code>sort</code> method on the collection. <code>sort</code> will fire a <code>reset</code> event, which you can use in your view to re-render the list.</p> <p>Here is my view, which contains a select box that allows the user to choose how to sort the data:</p> <pre><code>App.HouseListView = Backbone.View.extend({ el: '.house-list', initialize: function() { App.houseCollection.bind('reset', this.populateList, this); }, events: { 'change .sort':'sort', }, populateList: function(collection) { this.$('ul').html(''); _.each(collection.models, function(model) { var view = new App.HouseListElemView({model:model}); this.$('ul').append(view.el); }); }, sort: function(e) { var sort_by = $(e.srcElement.selectedOptions[0]).attr('data-sort-by'); App.houseCollection.comparator = function(house) { return house.get(sort_by); } App.houseCollection.sort(); }, }); </code></pre> <p>Hope this helps</p> <p>EDIT: Implemented <code>@mu is too short</code>'s suggestion:</p> <pre><code>App.Houses = Backbone.Collection.extend({ model: App.House, url: API_URL, _sort_by: 'price', sort_houses_by: function(sort_by) { this._sort_by = sort_by; this.sort(); }, comparator: function(house) { return house.get(this._sort_by); }, }); App.houseCollection = new App.Houses(); App.HouseListView = Backbone.View.extend({ el: '.house-list', initialize: function() { App.houseCollection.bind('reset', this.populateList, this); }, events: { 'change .sort':'sort', }, populateList: function(collection) { this.$('ul').html(''); _.each(collection.models, function(model) { var view = new App.HouseListElemView({model:model}); this.$('ul').append(view.el); }); }, sort: function(e) { var sort_by = $(e.srcElement.selectedOptions[0]).data('sort-by'); App.houseCollection.sort_houses_by(sort_by); }, }); </code></pre>

    1. COA method on the collection to swap the `comparator` and `sort` would be a better approach; then that method could just set `this._sort_by` and the `comparator` would `return house.get(this._sort_by)`. And you can just say `.data('sort-by')` instead of `.attr('data-sort-by')`.

    3. COshould populateList() be render() instead?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
