:white_check_mark: Single Selection
:white_check_mark: Multiple
:white_check_mark: Header
:white_check_mark: Options Footer
:white_check_mark: Filtered
:white_check_mark: Filtered Picked
:white_check_mark: Filtered Placeholder
:x: Custom List Options (very easy / trivial; needs rework of the story)
:x: Individual Custom Option (very easy / trivial; needs rework of the story)
:white_check_mark: Custom Button Text
:white_check_mark: Source Empty Placeholder
:white_check_mark: Picked Empty Component
:white_check_mark: Reordering
:x: Increased Options Height (very easy / trivial; but has the risk of not working cross-browser)
:white_check_mark: Different Widths
:white_check_mark: Custom Filtering With Filter Input
:white_check_mark: Custom Filtering Without Filter Input
:x: Infinite Loading (the only issue that's not trivial)
