Element pl-multiple-choice: Input of multiple choice answers

Questions below were designed to showcase the different features of pl-multiple-choice. The goal of pl-multiple-choice is to allow users to select a single option from a list of choices. To allow for more than one option, please consider using pl-checkbox.

Part 1

Here, you can observe the default behavior of the pl-multiple-choice element. In particular, all options are presented in a randomized form. Only one option may be selected from the list.

Part 2

Here, the pl-multiple-choice element is restricted to displaying 4 choices with one of the choices being the correct answer. In addition, the choices are placed "inline" instead of being displayed within a list. We also set hide-score-badge="True" to hide the partial score percentage and badge.

Part 5

Here, the pl-multiple-choice element displays "All of the above" and "None of the above" as options below the correct and incorrect options provided.

The number of options displayed is also consistent across all variants, and is determined automatically if number-answers is not set.
