                    You can customize the visual appearance of the options list <code>.combobox-results</code>, option heights, text alignment, input styles, borders, icons, and colors. The functional classes (like <code>.combobox-input</code>, <code>.combobox-value</code>, <code>.combobox-item</code>) must remain intact, and each item must include the <code>data-id</code>, <code>data-name</code>, and <code>tabindex="0"</code> attributes so they participate in keyboard selection cycling and updates.
