Paginated Combo Box

I have huge data for a simple default HTML combo box of, say 3000+, and unfortunately I cannot minify the data. It's just that I can populate a combo box with 3000+ records, but I want the data to be displayed paginated. What's the best way to achieve this requirement. Below are the pictures I want to achieve. I don't want a good GUI, just pagination would be fine.

This is the default look and feel for sockets, no pagination.

I want to get a breakdown of my results via JSON or any other source like the example below.
