        You can use ComboBoxes to select from lists of numbers:
      </p>
      <div className="form-group">
        <label>
          Select a number:
          <ComboBox itemsSource={numbers} selectedIndexChanged={(sender) => {
            setNumber(sender.selectedItem);
        }}>
          </ComboBox>
        </label>
      </div>
      <p>
        You have selected this number: <b>{number}</b>.
      </p>
      <hr />
      <p>
        You can use ComboBoxes to select from lists of dates.
        In this case, we use the <b>formatItem</b> event to format the date objects
        using Wijmo's <b>Globalize</b> class:
      </p>
      <div className="form-group">
        <label>
          Select a date:
          <ComboBox itemsSource={dates} formatItem={(sender, e) => {
            e.item.textContent = Globalize.format(e.data, 'd');
        }} selectedIndexChanged={(sender) => {
            setDate(sender.selectedItem);
        }}>
          </ComboBox>
        </label>
      </div>
      <p>
