Hello Yih Wern,
The attached image is too small for us to get an idea on whether the Grid and the Hoverable DropDown are somehow related.
Could you provide more details on your scenario? Is the Hoverable DropDown nested within the Grid, for example using a template, or it is independent of the Grid and declared outside of it? Do you use Kendo UI classes within the Hoverable DropDown, or it is created exactly as demonstrated on the page you linked.
Regards,
Ivan Danchev
