Hi,
the promotion product template uses the following grid classes to render the promotion product:
<div class="grid__col-lg-@columnSize grid__col-md-@columnSize grid__col-sm-@columnSize grid__col-xs-6">
The problem is that grid__col-xs-6 doesn't split products into 2 coloums on small mobile phones. It's the same problem/behaviour on the rapido demo site http://rapidodemo.dynamicweb-cms.com/frontpage
Any ideas?
