Hi,

I have a requirement like, when we type any person name its has to suggest person names along with email, it is like 2 level sugsestion.
It is like menu type structure

For ex:

If i type Mahsesh it has to suggest all names start with mahesh along with email id's in next level. Please find attached file

It will be helpful, if you can provide the code which supports this feature.
