In LibreWriter I want to create a multiple leveled checkbox. The default checkbox is thicked when activated and empty when not activated. I want to have an empty checkbox, when clicked on it it would be thicked, and when clicked on again it would have a cross mark “x” on it. Then it would turn empty when clicked on once again.
e.g. ☐ → click on → → click on → ☒ → click on → ☐
Is it possible to create something like this?
Thank you for the help.
