| If the Form or Link is enclosed by the Zone itself, then the {{zone}} parameter may be set to the special value {{^}}. The carat is evaluated, on the client side, by searching up form the form or link element for the first enclosing element with the {{t-zone}} CSS class. In this way, the client-side coordination can occur without having to know what the specific client-side id of the Zone is. Because of this, in many cases, it is no longer necessary to specify the Zone's {{id}} parameter. |
