My Answer:
options that allow users to select multiple items at once. This can be achieved by using the "multiple" attribute in the tag in HTML. Here is an example code snippet:

Option 1
Option 2
Option 3



In this example, users can hold down the Ctrl key (or Command key on Mac) while clicking on the options to select multiple items. Alternatively, users can click and drag to select multiple items at once.
