It has been made for the UNA 11.0.0. NOw we have 11.0.4 so please specify what troubles did you meet with it?
Try to go to Studio->Lucid->Styles->Custom Styles area and add there the following lines:
height: auto;
}
Is that supposed to stop the scrollable menu? Doesn't look to have worked.
Working now - how do we do the drop down menus? thanks for your help appreciate it
