The <rich:accordion> is a series of panels stacked on top of each other, each collapsed such that only the header of the panel is showing. When the header of a panel is clicked, it is expanded to show the content of the panel. Clicking on a different header will collapse the previous panel and epand the selected one. Each panel contained in a <rich:accordion> component is a <rich:accordionItem> component.

The <rich:accordionItem> component is a panel for use with the <rich:accordion> component. <rich:accordionItem> components can be added dynamically using iteration models with the <c:forEach> tag.

The <rich:autocomplete> component is an auto-completing input-box with built-in Ajax capabilities. It supports client-side suggestions, browser-like selection, and customization of the look and feel.

The <rich:calendar> component allows the user to enter a date and time through an in-line or pop-up calendar. The pop-up calendar can navigate through months and years, and its look and feel can be highly customized.

The <rich:collapsiblePanel> component is a collapsible panel that shows or hides content when the header bar is activated. It is a simplified version of <rich:togglePanel> component.

The <rich:collapsibleSubTable> component acts as a child element to a <rich:dataTable> component. The <rich:collapsibleSubTable> component iterates through the child collections in the currently iterated object to create master-detail tables.

The <rich:collapsibleSubTableToggler> component provides a toggle control for the user to expand and collapse sub-tables.

The <rich:column> component facilitates columns in a table. It supports merging columns and rows, sorting, filtering, and customized skinning.

The <rich:columnGroup> component combines multiple columns in a single row to organize complex parts of a table. The resulting effect is similar to using the breakRowBefore attribute of the <rich:column> component, but is clearer and easier to follow in the source code.

The <rich:componentControl> behavior allows JavaScript API functions to be called on target components. The functions are called after defined events are triggered on the component to with the <rich:componentControl> behavior is attached. Initialization variants and activation events can be customized, and parameters can be passed to the target component.

The <rich:contextMenu> component is used for creating a hierarchical context menu that are activated on events like onmouseover, onclick etc. The component can be applied to any element on the page.

The <rich:dataGrid> component is used to arrange data objects in a grid. Values in the grid can be updated dynamically from the data model, and Ajax updates can be limited to specific rows. The component supports header, footer, and caption facets.

The <rich:dataScroller> component is used for navigating through multiple pages of tables or grids.

The <rich:dataTable> component is used to render a table, including the table's caption. It works in conjunction with the <rich:column> and <rich:columnGroup> components to list the contents of a data model.

The <rich:dragIndicator> component defines a graphical element to display under the mouse cursor during a drag-and-drop operation.

The <rich:dragSource> component can be added to a component to indicate it is capable of being dragged by the user. The dragged item can then be dropped into a compatible drop area, designated using the <rich:dropTarget> component.

The <rich:dropTarget> component can be added to a component so that the component can accept dragged items. The dragged items must be defined with a compatible drop type for the <rich:dragSource> component.

The <rich:editor> component is used for creating a WYSIWYG editor on a page.

The <rich:extendedDataTable> component builds on the functionality of the <rich:dataTable> component, adding features such as scrolling for the table body (both horizontal and vertical), Ajax loading for vertical scrolling, frozen columns, row selection, and rearranging of columns. It also supports all the basic table features such as sorting, filtering, and paging using the <rich:dataScroller> component.

The <rich:fileUpload> component allows the user to upload files to a server. It features multiple uploads, progress bars, restrictions on file types, and restrictions on sizes of the files to be uploaded.

The <rich:graphValidator> component is used to wrap a set of input components related to one object. The object defined by the <rich:graphValidator> component can then be completely validated. The validation includes all object properties, even those which are not bound to the individual form components. Validation performed in this way allows for cross-field validation in complex forms.

The <rich:hashParam> component allows client-side parameters to be grouped into a hash map. The hash map can then be passed to the client JavaScript API functions of any RichFaces component.

The <rich:hotKey> component allows registering hot keys on the page or particular elements and defining client side processing functions for these keys.

The <rich:inplaceInput> component allows information to be entered in-line in blocks of text, improving readability of the text. Multiple input regions can be navigated with keyboard navigation. The component has three functional states: the view state, where the component displays its initial setting, such as "click to edit"; the edit state, where the user can input text; and the "changed" state, where the new value for the component has been confirmed but can be edited again if required.

The <rich:inplaceSelect> component is similar to the <rich:inplaceInput> component, except that the <rich:inplaceSelect> component uses a drop-down selection box to enter text instead of a regular text field. Changes can be rendered either in-line or for the whole block, and inputs can be focused with keyboard navigation. The component is based on the JSF UISelectOne component, so all the standard rules for value definition, processing, conversion, and validation apply.

The <rich:jQuery> component applies styles and custom behavior to both JSF (JavaServer Faces) objects and regular DOM (Document Object Model) objects. It uses the jQuery JavaScript framework to add functionality to web applications.

The <rich:list> component renders a list of items. The list can be an numerically ordered list, an un-ordered bullet-point list, or a data definition list. The component uses a data model for managing the list items, which can be updated dynamically.

The <rich:menuGroup> component represents an expandable sub-menu in a menu control. The <rich:menuGroup> component can contain a number of <rich:menuItem> components, or further nested <rich:menuGroup> components.

The <rich:menuItem> component represents a single item in a menu control. The <rich:menuItem> component can be also be used as a seperate component without a parent menu component, such as on a toolbar.

The <rich:menuSeparator> component represents a separating divider in a menu control.

The <rich:notify> component serves for advanced user interaction, using notification boxes to give the user instant feedback on what's happening within the application. Each time this component is rendered, a floating notification box is displayed in the selected corner of the browser screen.

Notifications emited by <rich:notify>, <rich:notifyMessage> and <rich:notifyMessages> are displayed in top-right corner of the screen by default.

It is <rich:notifyStack> which defines where messages will appear and handles their stacking.

Stack also provides way how to remove messages from screen - when stack is re-rendered, current notifications are destroyed, freeing place for new notifications.

The <rich:orderingList> is a component for ordering items in a list (client-side).

The <rich:panel> component is a bordered panel with an optional header.

The <rich:panelMenu> component is used in conjunction with <rich:panelMenuItem> and <rich:panelMenuGroup> to create an expanding, hierarchical menu. The <rich:panelMenu> component's appearance can be highly customized, and the hierarchy can stretch to any number of sub-levels.

The <rich:panelMenuGroup> component defines a group of <rich:panelMenuItem> components inside a <rich:panelMenu>.

The <rich:panelMenuItem> component represents a single item inside a <rich:panelMenuGroup> component, which is in turn part of a <rich:panelMenu> component.

The <rich:pickList> is a component for selecting items from a list. Additionally, it allows for the selected items to be ordered (client-side). From the client side perspective, items are added/removed from the source list, and removed/added to the target list.

The <rich:popupPanel> component provides a pop-up panel or window that appears in front of the rest of the application. The <rich:popupPanel> component functions either as a modal window which blocks interaction with the rest of the application while active, or as a non-modal window. It can be positioned on the screen, dragged to a new position by the user, and re-sized.

The <rich:progressBar> component displays a progress bar to indicate the status of a process to the user. It can update either through Ajax or on the client side, and the look and feel can be fully customized.

The <rich:select> component provides a drop-down list box for selecting a single value from multiple options. The <rich:select> component can be configured as a combo-box, where it will accept typed input. The component also supports keyboard navigation. The <rich:select> component functions similarly to the JSF UISelectOne component.

The <rich:tab> component represents an individual tab inside a <rich:tabPanel> component, including the tab's content. Clicking on the tab header will bring its corresponding content to the front of other tabs.

The <rich:tabPanel> component provides a set of tabbed panels for displaying one panel of content at a time. The tabs can be highly customized and themed. Each tab within a <rich:tabPanel> container is a <rich:tab> component.

The <rich:toggleControl> behavior can be attached to any interface component, whether inside or outside the controlled panel itself. It works with a <rich:togglePanel> component to switch between different <rich:togglePanelItem> components.

The <rich:togglePanel> component is used as a base for the other switchable components, the <rich:accordion> component and the <rich:tabPanel> component. It provides an abstract switchable component without any associated markup. As such, the <rich:togglePanel> component could be customized to provide a switchable component when neither an accordion component or a tab panel component is appropriate.

The <rich:togglePanelItem> component is a switchable panel for use with the <rich:togglePanel> component. Use the <rich:togglePanelItem> component to define the content for a panel using nested components. Switching between <rich:togglePanelItem> components is handled by the <rich:toggleControl> behavior.

The <rich:toolbar> component is a horizontal toolbar. Any JavaServer Faces (JSF) component can be added to the toolbar.

The <rich:toolbarGroup> component is a child component of the <rich:toolbar> component. The <rich:toolbarGroup> component is used to group a number of items together on a toolbar.

The <rich:tooltip> component provides an informational tool-tip. The tool-tip can be attached to any control and is displayed when hovering the mouse cursor over the control.

The <rich:tree> component provides a hierarchical tree control. Each <rich:tree> component typically consists of <rich:treeNode> child components. The appearance and behavior of the tree and its nodes can be fully customized.

The component iterates through recursive collections in order to populate a tree with hierarchical nodes, such as for a file system with multiple levels of directories and files.

The component is a child component of the component. It represents nodes in the parent tree. The appearance and functionality of each tree node can be customized.

The rich:isUserInRole(Object) function checks whether the logged-in user belongs to a certain user role, such as being an administrator. User roles are defined in the web.xml settings file.
