Description

2. Should have a property that holds the index of the item selected.
3. Should have a readonly property that holds the list of values.
4. Should have a method that can be used to clear the list.

6. An item should show that they are selected.

Unit Tests

Reasons for local unit test execution:

• Unit tests might pass locally but not in the CI environment during the status check process or vice-versa.
• Tests might pass on the developer's machine but not necessarily on the code reviewer's machine.
• If you notice that the test status check has passed but the test failed locally, please notify a project maintainer!

💡Warning💡
If the unit tests pass remotely and are not executed locally, this means we could be letting a bug slip into production.
Though bugs will always exist in some capacity, we should all do our part to help prevent them from happening.
