Synopsis
This action works with a
switch element,
selecting by IDREF a particular
case within. The selected
case is rendered, while all other
cases are not. The ability to show and hide
sections is a handy way to implement a “multiple
page” form, which guides the user through one
section at a time. It’s also useful within a page,
to set up wizard-like sequences, or just to hide entire sections of
the form that aren’t needed at the moment.
Each case contains a selected
attribute, which stays in sync, so that at any given time one and
only one of the cases in a
switch will have
selected="true“. In fact, in systems that support
CSS2 selectors, one possible implementation is with the rule
case[selected="false"] { display: none }.
The toggle action is used like this:
<toggle case="summary" ev:event="DOMActivate"/>
