JS multiselect с кнопками удаления выбранных option
 

Подскажите, как реализовать что б по option:checked добавлялась нужная кнопка в верхнем блоке, а по её нажатию она бы убиралась из select, ну и выбранный options становился unchecked ? Пока удалось только показывать одну кнопку, а необходим массовый вывод
