Take look at my code. It makes the font size smaller to fit whatever there.

But I think this doesn't lead to a good user experience

var containerWidth = $("#ui-id-2").width();
var items = $(".quickSearchAutocomplete .ui-menu-item");
var fontSize = 16;

items.each(function(){
    // Displaying a value depends sometimes on your case. You may make it block or inline-table instead of inline-block or whatever value that make the div take overflow width.
    $(this).css({"whiteSpace": "nowrap", "display": "inline-block"});
    while ($(this).width() > containerWidth){
         console.log("$(this).width()" + $(this).width() + "containerWidth" + containerWidth)
         $(this).css("font-size", fontSize -= 0.5);
    }
});
