Backbone.PickySitter Example

var SelectView = Marionette.ItemView.extend({

    initialize: function(options) {
        this.bindTo(this, "selected", onSelect);
        this.bindTo(this, "deselected", onDeselect);
    },

    onSelect: function() {
        this.model.fetch();
    },

    onDeselect: function() {
        this.model.save();

var viewCont = new SelectableContainer();
// add some SelectViews

var myLayout = new Marionette.Layout({

    regions: {
        childRegion: "#myRegionId"
    },

        this.bindTo(viewCont, "select", showChildView, this);
