hello everybody,

i'm looking for a technique to adapt a html listbox to hierarchical content with an unlimited number of levels ( const > 1 would be sufficient ). hierarchy levels should be collapsible as in the usual file explorer views. the html listbox behaviour should be preserved / mimicked as comprehensively as possible. do you have a hint on where to find or how to implement this ? jquery solutions are fine.

firefox 3.5+, ie 8+, safari 5 must be supported; opera 11, chrome 9 would be nice.

as far as i understand the issue, listbox contents are rendered inside their own browser window sporting none of the standard window adornments. a hint on how to obtain a handle on this window in js would be a sufficient starting point, as well as correcting me in case i misconceived the browser behaviour.

thanks in advance for your efforts,

best regards,

carsten
