## Creating the Component with a Page Tag

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

Example:

    ...
        <rich:dataDefinitionList value="#{bean.capitals}" var="caps">
            <f:facet name="term">Cars</f:facet>
            <h:outputText value="#{car.model}"/>
        </rich:dataDefinitionList>
    ...

## Creating the Component Dynamically Using Java

Example:

    import org.richfaces.component.html.HtmlDataDefinitionList;
    ...
    HtmlDataDefinitionList myList = new HtmlDataDefinitionList();
    ...

## Details of Usage

The <rich:dataDefinitionList> component allows to generate an definition list from a model.

The component has the "term" facet, which corresponds to the "type" parameter for the <DT> HTML element.

Here is an example:

    ...
        <h:form>
            <rich:dataDefinitionList var="car" value="#{dataTableScrollerBean.allCars}" rows="5" first="4" title="Cars">
                <f:facet name="term">
                    <h:outputText value="#{car.make} #{car.model}"></h:outputText>
                </f:facet>
                <h:outputText value="Price:" styleClass="label"></h:outputText>
                <h:outputText value="#{car.price}" /><br/>
                <h:outputText value="Mileage:" styleClass="label"></h:outputText>
                <h:outputText value="#{car.mileage}" /><br/>
            </rich:dataDefinitionList>
        </h:form>
    ...

This is a result:

<rich:dataDefinitionList> component with "term" facet

In the example the "rows" attribute limits number of output elements of the list.

"first" attribute defines first element for output. "title" are used for popup title.

The component was created basing on the <a4j:repeat> component and as a result it could be partially updated with Ajax. The "ajaxKeys" attribute allows to define row keys that are updated after an Ajax request, you need to pass an array with key (lines) of the list that you want to be updated after the Ajax request is executed.

Here is an example:

Example:

    ...
        <rich:dataDefinitionList value="#{dataTableScrollerBean.allCars}" var="car" ajaxKeys="#{listBean.list}"
                            binding="#{listBean.dataList}" id="list">
            ...
        </rich:dataDefinitionList>
    ...
        <a4j:commandButton action="#{listBean.action}" reRender="list" value="Submit"/>
    ...

In the example "reRender" attribute contains value of "id" attribute for <rich:dataDefinitionList> component. As a result the component is updated after an Ajax request.

## 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:dataDefinitionList> components at once:

- Redefine the corresponding skin parameters

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

## Definition of Custom Style Classes

On the screenshot there are classes names that define styles for component elements.

Style classes

Classes names that define a list appearance

Class name | Description
--- | ---
rich-deflist | Defines styles for an html <dl> element
rich-definition | Defines styles for an html <dd> element
rich-definition-term | Defines styles for an html <dt> element

In order to redefine styles for all <rich:dataDefinitionList> 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-definition-term{
    	font-weight:bold;
    }
    ...

This is a result:

Redefinition styles with predefined classes

In the example a term font weight was changed.

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

Example:

    ...
    .myClass{
    	font-style: italic;
    }
    ...

Example:

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

This is a result:

Redefinition styles with own classes and styleClass attributes

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