When the website is viewed on a mobile the modules assigned to sidebar-a and to sidebar-b appear after the article content.
If I assign a module to position feature-a it appears at the top.
Is there a way to assign a module so that it appears in a sidebar when viewed from a large screen and appears in position feature-a when viewed from a phone?
I realise that one way would be to have two copies of the module, one displayed in a sidebar but not shown on a mobile and the other displayed in a feature position but only shown for a mobile.,
