            AutoComplete can work with objects using the <i>optionLabel</i> property that defines the label to display as a suggestion. The value passed to the model would still be the object instance of a suggestion. Here is an example with a
            Country object that has name and code fields such as <i>&#123;name: "United States", code:"USA"&#125;</i>.
