Figure 6.173. <rich:orderingList> component

#### 6.12.2.2. Key Features

- Highly customizable look and feel

- Reordering possibility for list items

- Multiple selection of list items

- Keyboard support

#### 6.12.2.3. 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.
