Description
The contrib:Choose component is used in conjunction with contrib:When and contrib:Otherwise components to express mutually exclusive conditional tests.

The contrib:Choose component must contain one or more contrib:When components and can contain only one optional contrib:Otherwise component (which must occur after all of the contrib:When components). If the contrib:Choose component only contains one contrib:When element, then for all practical purposes, it behaves just like the Conditional component. When faced with three or more choices, this component behaves like a switch/case/default statement.

Each contrib:When component is examined in the order of occurrence. If and when the condition expression is satisfied the content in that component is rendered. Then all further contrib:When components are ignored. The optional contrib:Otherwise component is also automatically ignored. If none of the conditions in any contrib:When component is satisfied , then the contrib:Otherwise component is automatically selected (if it is present) and the content associated with that element is rendered.

• White spaces
  May appear anywhere around the When and Otherwise components.
• 1 or more When components
  Must all appear before Otherwise.
• 0 or 1 Otherwise component
  Must be the last component nested within Choose

For simple conditional testing, use the Conditional component.

The following sample code shows how the text rendered depends on a user’s membership category.

              <span jwcid="@contrib:Choose>
                 <span jwcid="@contrib:When" condition='ognl:"visitor".equals(user.category)'>
                    ...
                 </span>
                 <span jwcid="@contrib:When" condition='ognl:"member".equals(user.category)'>
                    ...
                 </span>
                 <span jwcid="@contrib:When" condition='ognl:"customer".equals(user.category)'>
                    <span jwcid="@contrib:Choose>
