Hi Josh Pham,
Thank you for reaching out to us. We would like to ask
if you could please share the exact scenario in which you need to disable a
dropdown item. Since we are using a List, we are unable to disable a specific
item in the dropdown. However, if you are referring to a different scenario for
disabling, please provide us with the exact details so we can offer you a more
precise solution.
Regarding hiding the vertical scroll, unfortunately,
it is not possible because we cannot access the ListView of the dropdown in the
SfComboBox.
Please feel free to reach out if you have any further
questions or concerns.
Best regards,
Hariharan C.
