DOM innerHTML equivalent ?

[jbv at souslelogo.com]

Hi list,

Is there a way to catch all controls on a card
(for instance) with all their properties and
values, and store them in a variable, like
innerHML for a DOM element, and have all these
controls displayed later very fast and in one go ?

I hope I made myself clear.
I tried several things, like storing all properties
and values as text in a variable and then recreating
all controls (quire slow), or duplicate the controls
on a hidden card or another stack, but nothing is as
easy as what is available i the DOM.

Thank you in advance.
