Detailed Description
A list of options, separated by '|'.This widget is part of the Wt composer example.
An OptionList displays a list of Option widgets, which are separated by a '|' separator.
For example, Foo | Bar | Huu
When Options are hidden, the separators are adjusted so that there is no separator after the last visible option. However, this requires a call of update() each time an option is hidden or shown. This is because the removing of separators is optimized in stateless implementations, and thus in client-side JavaScript code. Since the behaviour is not entirely stateless, the update() method resets stateless implementations if necessary.
