Hi Rob,

if i understand you correct, you want change your options
in your select box triggerd by an  KSS-Event, right?

If thats your usecase you can do something like this:
(it´s not tested)

for x in YOUR_NEW_OPTIONS:
              result.extend(['<option value="%s">%s</option>' %(x[0],x[1])])
              IKSSComands.replaceInnerHTML('licenseClass', ' '.join(result))


But i don´t know if it´s the right way to do it??
