HighSlide - Change width of an opened popup

Question

How can I change the width (fixed dimension in px) of a currently opened popup? Let's say from 400px to 600px.

Tried this, but doesn't work:

var expander=hs.getExpander(jq('#my_popup_id_HS')[0]);
hs.maxHeight=600;
expander.reflow();

Answer 1

Try .height instead of .maxHeight
