| Attributes |
| Name | Required | Request-time | Type | Description |
| url | true | false | java.lang.String | Top of the nav bar |
| title | true | false | java.lang.String | Top of the nav bar |
| id | false | false | java.lang.String | The developer-assigned ID of this component. The ID must be unique within the scope of the tag's enclosing naming container (e.g. h:form or f:subview). This value must be a static value. |
| binding | false | false | java.lang.String | Identifies a backing bean property (of type UIComponent or appropriate subclass) to bind to this component instance. This value must be an EL expression. |
| rendered | false | false | java.lang.String | A boolean value that indicates whether this component should be rendered. Default value: true. |
| action | false | false | java.lang.String | A method binding EL expression that identifies an action method to be invoked if this component is activated by the user. An action method accepts no parameters and has a String return value, called the action outcome, that identifies the next view displayed. The phase that this event is fired in can be controlled via the immediate attribute. |
| actionListener | false | false | java.lang.String | A method binding EL expression that identifies an action listener method to be invoked if this component is activated by the user. An action listener method accepts a parameter of type javax.faces.event.ActionEvent and returns void. The phase that this event is fired in can be controlled via the immediate attribute. |
| immediate | false | false | java.lang.String | A boolean value that identifies the phase during which action events should fire. During normal event processing, action methods and action listener methods are fired during the "invoke application" phase of request processing. If this attribute is set to "true", these methods are fired instead at the end of the "apply request values" phase. |
| value | false | false | java.lang.String | The initial value of this component. |
