#### 6.6.5.3. Details of Usage

The dataFilterSlider component is bound to some UIData component using a "for" attribute and filters data in a table.

Example:

    ...

    <rich:dataFilterSlider sliderListener="#{mybean.doSlide}"

                            startRange="0"

                            endRange="50000"

                            increment="10000"

                            handleValue="1"

                            for="carIndex"

                            forValRef="inventoryList.carInventory"

                            filterBy="getMileage" />

    ...

    <h:dataTable id="carIndex">

            ...

    </h:dataTable>

    ...

In this example other two attributes are used for filtering:

- "forValRef" is a string which is used in a value attribute of the target UIData component. It's designed for resetting the UIData component back to the original list provided by a backing bean.

- "filterBy" is a getter of an object member that is to be compared to a slider value. It's a value that is used in results filtering.

"handleValue" is an attribute for keeping the current handle position on the dataFilterSlider component. Based on the current value, appropriate values obtained from a getter method defined in "filterBy" are filtered.

One more important attribute is a "storeResults" one that allows the dataFilterSlider component to keep UIData target object in session.

If it's necessary the component submits a form on event of a handle state changing, use the "submitOnSlide" attribute. When the attribute definition is `"true"`, submission on this event is defined.

Information about the "process" attribute usage you can find in the "Decide what to process " guide section.
