+/**
+ * A split button that provides a built-in dropdown arrow that can fire an event separately from the default click event
+ * of the button. Typically this would be used to display a dropdown menu that provides additional options to the
+ * primary button action, but any custom handler can provide the arrowclick implementation. Example usage:
+ *
+ * @example
+ * // display a dropdown menu:
+ * Ext.create('Ext.button.Split', {
+ * renderTo: Ext.getBody(),
+ * text: 'Options',
+ * // handle a click on the button itself
+ * handler: function() {
+ * alert("The button was clicked");
+ * },
+ * menu: new Ext.menu.Menu({
+ * items: [
+ * // these will render as dropdown menu items when the arrow is clicked:
+ * {text: 'Item 1', handler: function(){ alert("Item 1 clicked"); }},
+ * {text: 'Item 2', handler: function(){ alert("Item 2 clicked"); }}
+ * ]
+ * })
+ * });
+ *
+ * Instead of showing a menu, you can provide any type of custom functionality you want when the dropdown
+ * arrow is clicked:
+ *
+ * Ext.create('Ext.button.Split', {
+ * renderTo: 'button-ct',
+ * text: 'Options',
+ * handler: optionsHandler,
+ * arrowHandler: myCustomHandler
+ * });
+ *
