In muse using "expand browser-width" and works well. I have trouble when I create content in animated edge. It's possible set up in animated edge 2015.0 "expand browser width"?
but to get some answers you have to complain and begging? Yet it is an official forum.
Go to your properties box and check the tick box 'Responsive Scaling' you will then get the option of width by default but this can be changed to height or both depending on your preference.
unfortunately is a function sour that not does well his job
