Hi Tullio,

if you have dropdownlists, by default the popup is part of the dropdownlist and if there is not enough available space, the dropdown will not be fully visible. You can optionally display it, if the dropdown is added to the document’s body. The dropdownlist has a property called ‘dropDownAppendTo’. If you set it to body, the dropdown will be added to the document’s body so it will always be on top of other elements.

Best regards,
