Will the Attributes filter work with a dropdown element instead of a select element?

Webflow Dropdown elements aren't supported by Finsweet's Attributes filter, since it requires a native <select> element or standard form inputs.

If you want to use a dropdown-style filter, you can use Custom Form Select as a workaround. It lets you style a Webflow Dropdown while keeping a real <select> in the background, which Attributes can detect and use for filtering.
