Hi Masroorul,

For SharePoint dropdown list control, there is no property can set the scrollbar for the control.

As a workaround, we can create a css style and the wrap the multiple option value for the dropdownlist control to display the scrollbar.

Here is a demo for your reference:

html select scroll bar

For the duplicated values in dropdownlist, I would suggest you can check the dropdown list datasource and make sure the values in datasource is unique.

Populate a Drop Down List with Unique Values from a list

Thanks

Best Regards
