I’ve Drupal Development Company subsequent type which habits is:
-
When you choose an choice from choose management, totally different checkbox are load on checkboxes management.
-
Once you test/uncheck checkbox a message is confirmed on Drupal Development Company botton with data about choose worth and checkbox clicked.
Every little thing works positive, however is not possible test by default a checkbox from checkboxes management after ajax operate.
Any thought?
