Checkout jquery-ui's autocomplete here

use keydown event before autocomplete

.bind( "keydown", function( event ){
                if ( event.keyCode === $.ui.keyCode.TAB &&
                        $( this ).data("autocomplete").menu.active ) {
                        event.preventDefault();
                }
            })
            .autocomplete({

here on tab press it will be selected
