Seaside.WATree expand and element position

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,

It is very hard to read your HTML mails, could you please configure
your client to send plain text?

Something like that should work:

html render: component.

Or with a styled div:

html div style: 'blabla'; with: component

The thing is that you should never call render methods of other
components, just give the component to Seaside and let the framework
do the setup.

Scriptaculous package in the Seaside repository. Live demo at
