expand all

#### 6.10.15.1. Description

Figure 6.106. <rich:togglePanel> component

#### 6.10.15.2. Key Features

- Support for any content inside

- Three modes of facets switching

  - `Server`

  - `Client`

  - `Ajax`

- Controls for togglePanel can be everywhere in layout

#### 6.10.15.3. Details of Usage

As it was mentioned above, togglePanel splits content into named facets that become rendered and processed when a click performed on controls linked to this togglePanel (either switched on the client or send requests on the server for switching).

The initial component state is defined with "initialState" attribute, where a facet name that is shown at first is defined.

## Note:

It's also possible to define an "empty" facet to implement the functionality as drop-down panels have and make the facet active when no content is required to be rendered.

Switching mode could be defined with the "switchType" attribute with three possible parameters:

- `Server` (DEFAULT)

  The common submission is performed around togglePanel and a page is completely rendered on a called panel. Only one at a time the panel is uploaded onto the client side.

- `Ajax`

  AJAX form submission is performed around the panel, content of the called panel is uploaded on an Ajax request . Only one at a time the panel is uploaded on the client side.

- `Client`

  All panels are uploaded on the client side. The switching from the active to the hidden panel is performed with client JavaScript.

"Facets" switching order could be defined on the side of <rich:toggleControl> component or on the panel. On the side of the togglePanel it's possible to define facets switching order with the "stateOrder" attribute. The facets names are enumerated in such an order that they are rendered when a control is clicked, as it's not defined where to switch beforehand.

Example:

    ...

    <rich:togglePanel id="panel" initialState="panelB" switchType="client"

                            stateOrder="panelA,panelB,panelC">

            <f:facet name="panelA">

                    ...

            </f:facet>

            <f:facet name="panelB">

                    ...

            </f:facet>

            <f:facet name="panelC">

                    ...

            </f:facet>

    </rich:togglePanel>

    <rich:toggleControl for="panel" value="Switch"/>

    ...

The example shows a togglePanel initial state when the second facet (`panelB`) is rendered and successive switching from the first to the second happens.

The "label" attribute is a generic attribute. The "label" attribute provides an association between a component, and the message that the component (indirectly) produced. This attribute defines the parameters of localized error and informational messages that occur as a result of conversion, validation, or other application actions during the request processing lifecycle. With the help of this attribute you can replace the last parameter substitution token shown in the messages. For example, {1} for `"DoubleRangeValidator.MAXIMUM"`, {2} for `"ShortConverter.SHORT"`.
