### 6.74.3. Creating the Component with a Page Tag

To create the simplest variant on a page use the following syntax:

Example:

    ...

    <rich:orderingList value="#{bean.list}" var="list">

            <rich:column>

                <f:facet name="header">

            <h:outputText value="Name" />

                </f:facet>

                <h:inputText value="#{list.name}" />

            </rich:column>

    <rich:orderingList>

    ...

### 6.74.4. Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlOrderingList;

    ...

    HtmlOrderingList myOrderingList = new HtmlOrderingList();

    ...

### 6.74.5. Details of Usage

The <rich:orderingList> component consists of

- Item list element that displays a list of items. It has three different representations for a single element: common, selected, active. Combination of these states is possible.

- Ordering controls set

The "value" and "var" attributes are used to access the values of a list.

Controls rendering is based on the "controlsType" attribute. Possible types are button or none.

## Note

Currently the button controls type is based on <div> element.

The information about the "converter" attribute is here.

The "selection" attribute stores the collection of items selected by you. In the example below after submitting the form the current collection is placed in the object's property and then <rich:dataTable> with selected items is shown.

Example:

    ...

    <h:form>

            <rich:orderingList value="#{bean.simpleItems}" var="item" selection="#{bean.selection}" controlsType="button">

                    <rich:column>

                        <f:facet name="header">

                                <h:outputText value="Cars" />

                        </f:facet>

                                <h:outputText value="#{item}" />

                    </rich:column>

            </rich:orderingList>

            <rich:dataTable id="infoPanelID" value="#{bean.info}" var="info" rendered="true">

                    <rich:column>

                                <h:outputText value="#{info}" />

                    </rich:column>

            </rich:dataTable>

            <a4j:commandButton value="reRender" reRender="infoPanelID" />

    </h:form>

    ...

The <rich:orderingList> component allows to use "caption" facet. A caption could be also defined with "captionLabel" attribute.

Simple example is placed below.

Example:

    ...

    <rich:orderingList value="#{bean.simpleItems}" var="item" controlsType="button" selection="#{bean.selection}">

            <f:facet name="caption">

                    <h:outputText value="Caption Facet" />

            </f:facet>

            <rich:column>

                    <f:facet name="header">

                    <h:outputText value="Cars" />

                    </f:facet>

                    <h:outputText value="#{item.name}" />

            </rich:column>

            <rich:column>

                    <f:facet name="header">

                    <h:outputText value="Price" />

                    </f:facet>

                    <h:outputText value="#{item.price}" />

            </rich:column>

    </rich:orderingList>

    ...

The <rich:orderingList> component provides the possibility to use ordering controls set, which performs reordering. Every control has possibility to be disabled.

An ordering controls set could be defined with "topControlLabel" , "bottomControlLabel" , "upControlLabel" , "downControlLabel" attributes.

It is also possible to use "topControl" , "topControlDisabled" , "bottomControl" , "bottomControlDisabled" , "upControl" , "upControlDisabled" , "downControl" , "downControlDisabled" facets in order to replace the default controls with facets content.

Example:

    ...

    <rich:orderingList value="#{bean.simpleItems}" var="item" controlsType="button" selection="#{bean.selection}">

            <f:facet name="topControl">

                    <h:outputText value="Move to top" />

            </f:facet>

            <f:facet name="upControl">

                    <h:outputText value="Move up" />

            </f:facet>

            <f:facet name="downControl">

                    <h:outputText value="Move down" />

            </f:facet>

            <f:facet name="bottomControl">

                    <h:outputText value="Move to bottom" />

            </f:facet>

    <rich:orderingList>

    ...

The position of the controls relatively to a list could be customized with:

- "controlsHorizontalAlign" attribute. Possible values:

  - "left" - controls render to the left side of a list

  - "right" (default) - controls render to the right side of a list

  - "center" - controls is centered

- "controlsVerticalAlign" attribute. Possible values:

  - "top" - controls render aligned to the top side of a list

  - "bottom" - controls render aligned to the bottom side of a list

  - "center" (default) - controls is centered relatively to a list

The <rich:orderingList> component has a possibility to hide any of the controls by pairs using following attributes:

- "orderControlsVisible" attribute has two values: "true" or "false". If false Up and Down controls are not displayed.

- "fastOrderControlsVisible" attribute has two values: "true" or "false". If false Top and Bottom controls are not displayed.

The <rich:orderingList> component allows to use internationalization method to redefine and localize the labels. You could use application resource bundle and define `RICH_SHUTTLES_TOP_LABEL`, `RICH_SHUTTLES_BOTTOM_LABEL`, `RICH_SHUTTLES_UP_LABEL`, `RICH_SHUTTLES_DOWN_LABEL` there.

You could also pack `org.richfaces.renderkit.orderingList` resource bundle with your JARs defining the same properties.

### 6.74.8. Look-and-Feel Customization

For skinnability implementation, the components use a style class redefinition method. Default style classes are mapped on skin parameters.

There are two ways to redefine the appearance of all <rich:orderingList> components at once:

- Redefine the corresponding skin parameters

- Add to your style sheets style classes used by a <rich:orderingList> component

In order to redefine styles for all <rich:orderingList> components on a page using CSS, it's enough to create classes with the same names (possible classes could be found in the tables above) and define necessary properties in them.

Example:

    ...

    .rich-ordering-list-table-header-cell{

            font-weight:bold;

    }

    ...

This is a result:

Figure 6.207. Redefinition styles with predefined classes

In the example the font weight for header text was changed.

Also it's possible to change styles of particular <rich:orderingList> component. In this case you should create own style classes and use them in corresponding <rich:orderingList> styleClass attributes. An example is placed below:

Example:

    ...

    .myClass{

            font-style:italic;

    }

    ...

The "rowClasses" attribute for <rich:orderingList> is defined as it's shown in the example below:

Example:

    <rich:orderingList ... rowClasses="myClass"/>

This is a result:

Figure 6.208. Redefinition styles with own classes and styleClass attributes

As it could be seen on the picture above, the font style for rows was changed.
