[Seaside] Seaside.WATree expand and element position

[Dario Trussardi]

Hi Lukas,

thanks for your indication.

I have add note in bold .

    Remove "renderTreeOn: html", you should never all render methods of
   other components. And since this method returns the component, it is
    displayed twice.

    OK BUT WHAT DO I USE ?
               When use [ html render: component] i see normall view; not in div space with scroll bar.

Yes, but it is probably not simple and certainly involves changing the
implementation of WATree. You could do it using JavaScript, e.g. with
script.aculo.us and a scroll-to effect.

Where i found dettail information and example about this ?


Thanks & Regards,
