The <apex: enhancedList> is another important component for displaying the list view picklist for an Object. It also displays the associated list of records for the currently selected view.
When this component rerendered through another component's reRender attribute:
It must be specified inside of an <apex: outputPanel> component.
The layout attribute must be set to block.

The <apex: enhancedList> has the following attributes:
1. customizable
