The modal stuff isn't part of the Full Calendar ui, but some simple css can be used to create the modals. For a more complete solution, you should also have a cancel button which would then trigger for the modal to be closed.
☒ If we just searched by column then when we moved an item from one column to a different one, it wouldn't be found. That's why we have to search based on the list instead of the column.
