In HTML5 there is a new input type, \'search\'.
On most browser it\'s just remain to a simple \'text\' input, but for webkit based browsers, it adds a little cross to reset
No, it's not possible. This UI interaction is some goodness that webkit implements, but is not actually specced. See here. So even if it were possible--you can't expect this UI to be implemented in Gecko, for example, if and when they ever add type=search.
