Hello Nagendra,

We noticed that your company has licenses for Kendo UI, but you are not added as a license developer.
Please ask the license holder to add you as such so you could use all benefits of the license. 

As to the question - could you please elaborate more on the question? Do you need to use a suggestion box as the Google's one? If this is the case, then I will suggest you check the AutoComplete widget.

Regards,
