When you create a new grid I know that you can define the number of columns by setting the 'width' in the options array.

For example:
$('.grid-stack').gridstack( {width: 3} );

Is there a way, through jQuery, to update this value to 2 for example.

I have tried:
$('.grid-stack').gridstack({ width: 2 });
$('.grid-stack').data('gridstack').width = 2;

Any ideas? Thanks
