I'm not seeing any documentation for this.
How do you manually select which panel is active in the wizard component?
I know it's in there somewhere because you can click on one of the tabs once it's been passed, and navigate back to a previous tab.
Yes, you can change wizard step:
$('#MyWizard').wizard('selectItem', { step: step });
UPDATE:
After the last updates now it works with selectedItem
$('#MyWizard').wizard('selectedItem', { step: step });
Note the change from select to selected*.
