Ok, so I managed to open a functioning carousel with image radiobuttons as elements. I also correctly registered jquery.touchSwipe.min, and declared the swipe option like this:
$this->widget('ext.ECarouFredSel', array(
'id' => 'carousel',
'target' => '#...',
'config' => array(
'auto' => false,
'width' => '50%',
'height' => 150,
'next' => 'right',
'prev' => 'left',
'swipe' => array('onMouse'=>true, 'onTouch'=>true)
),
));
But nothing happens. Scroll by keyboard works.
