Unable to select a result from the select2 search results

Question

I am using the select2 for on of my search boxes. I\'m getting the results from my URL but I\'m not able to select an option from it. I want to use the \'product.productName

Since I was using AJAX, what worked for me was returning something as the ID on processResults:

$(field).select2({
   ajax: {
        // [..] ajax params here
        processResults: function(data) {
            return {
                results: $.map(data, function(item) {
                    return {
                        // proccessResults NEEDS the attribute id here
                        id: item.code,
                        // [...] other attributes here
                        foo: item.bar,
                    }
                })
            }
        },
    },
});
