1. First, create a label for the dropdown box.
2. Initialize the label text with the current number of elements in the dropdown box.
3. Whenever a new element is added or removed from the dropdown box, update the label text to reflect the new number of elements. This can be done using a listener or callback function that triggers whenever the dropdown box is modified.
4. Make sure to update the label text after any modification to ensure that it always displays the correct number of elements within the dropdown box.
