Working with Checkboxes, Radio Buttons, and Dropdowns

Using DocumentFragment for batch updates is the most efficient way to handle dynamic option updates. Benefits: 1) Minimizes DOM reflows by making all changes off-document, 2) Better performance for large option sets, 3) Maintains element references and event listeners, 4) Reduces visual flickering, 5) Works well with frameworks' virtual DOM. Pattern: Create a fragment, append all new options to it, then append the fragment to the select element in a single operation. This is particularly important for dropdowns with many options or frequent updates.
