class
The CSS class, or classes, to assign to the weblet. A CSS class allows you to specify a set of CSS styles, defined in an external stylesheet, to apply to a weblet, or elements within a weblet. For complex weblets made from multiple HTML elements, the class is applied to the outermost element of the weblet.
To make the Navigation Bar persistent, add the value "ui-state-persist" to the class.
