toggle between two state
do you know if it's possible for a user to toggle between two states of an object by clicking on it? I'd like to have users select 10 items out of 48; once selected, the item state changes so the user can see which items have been selected. I've used a variable to count the total number of selected items, so that if more or less than 10 are selected, the user is warned. But I'd like the user to be able to click on the item a second time to revert to the original state, so they can change their mind on their selection. Is this possible in storyline?
