+      Use <code>&#123; lazyData: () => Promise &#125;</code> to lazy load data only after clicking and opening the select dropdown.

       You can refresh the page, or click the button to retest the lazy loading.
       Also note that any pre-selected options will only show up after the data is fully loaded.
