I'm trying to create a game for children in EPUB. I want to create some boxes they could drag and drop to the correct place. It is some kind of a game where you have to order words in a sentence.
From here I've learned that in EPUB it is probably possible only using JS.

Is there any way this could be done more easily in Sigil without programming (e.g. some plugin, ...)?
