You can switch selected accordion view programatically by calling ludo.get('<id-of-view>').show().
Call ludo.get('customStyling').show()
Call ludo.get('customStyling').hide()
You can also make some of the accordion views initially hidden and show them using the show method:
Call ludo.get('hiddenView').show()
To add a new child view programatically, use ludo.get('<id of parent'>).addChild(object);
Try it: ludo.get('accordionWindow').addChild({ 'title': 'New child', html: 'Child' })
