autohide Whether or not the dropdown hides automatically when the mouse moves away. Boolean true

Initializing a new drop-down button with an HTML string for content.

var dropdownButton = new SK.UI.Button.Dropdown( window, {
   caption : 'My Button',
   'class' : 'btn-primary',
   content : '<ul><li><a href="">Item 1</a><a href="">Item 2</a><a href="">Item 3</a></li></ul>'
}).inject( document.body );


Initializing a drop-down button that uses a DOM element for content and assigning an event. The event is handled in the manager object.

var dropdownButton = new SK.UI.Button.Dropdown( window, {
   caption : 'My Button',
   'class' : 'btn-primary',
   event   : 'action'
   content : '_$("element")'
}).inject( document.body );

window.addEvent('action', function () {
   alert('The dropdown button is clicked.');


Here is an example with the content as a function.

generateContent = function () {
   return '<ul><li><a href="">Item 1</a><a href="">Item 2</a><a href="">Item 3</a></li></ul>';

var dropdownButton = new SK.UI.Properties.DropDownButton( window, {
   caption : 'My Button',
   'class' : 'btn-primary',
   content : generateContent
}).inject( document.body );
