dhtmlx.message positioning problem

I tried to use options
top:‘10px’,
left:‘10px’
to position my notice messages, but it has never worked. The messages always appear on the top right corner.
I had to write my own css to position and style the messages.
Is there any way to use pure dhtmlx for it?

You can position alert or confirm boxes. Messages will alway appear at fixed position, so the only solution is the custom css.
