pl-dropdown element

Warning

Instructors are strongly encouraged to avoid pl-dropdown in newer questions. For questions with a single dropdown, a better alternative is to use pl-multiple-choice, setting the attribute display="dropdown". Using the multiple choice element provides better support for formatted option text (including Math formulas), randomized selection and ordering of options (both correct options and distractors) and partial scores for distractors. For questions using multiple dropdowns with the same set of options, the pl-matching element provides a better user experience and interface.

Select the correct answer from a drop-down select menu list of potential answers. The potential options are listed in the inner HTML of a <pl-answer></pl-answer> element (e.g. <pl-answer>Possible Answer 1</pl-answer>).
