The RichFaces Rich: OrderingList is a component that allows users to reorder a list of items. It is commonly used in web applications to allow users to sort and reorder data in a way that is easy and intuitive.

Features

The Rich: OrderingList component has a number of features that make it a powerful tool for web developers. These include:

• Drag and drop support: Users can simply drag and drop items in the list to reorder them.
• Keyboard support: Users can use the keyboard to move items up and down in the list.
• Add and remove items: Users can add and remove items from the list.
• Customizable styling: Developers can customize the look and feel of the component to match the rest of their application.

Usage

The Rich: OrderingList component can be easily added to any web application that uses the RichFaces framework. To use the component, simply include the following code in your application:

<rich:orderingList value="#{bean.listOfItems}"
                   var="item"
                   converter="#{richfacesBean.converter}"
                   listHeight="200">
    <rich:column>
        <h:outputText value="#{item}" />
    </rich:column>
</rich:orderingList>
