Why panel object when hidden render itself as <BR>

[George Ter-Saakov]

I have a composite control.
Which has 2 parts. Under some conditions first part must be shown sometimes
another. So naturally I used 2 Panel object.
And hide one of them.

The problem is that hidden Panel object renders itself as <br>. Not sure
what is the purpose of it. But it ads extra line which is not acceptable.

Is there another control which when hidden is HIDDEN and does not render
anything.

Thanks.
George.
