revealing the layers out of sequence.
I am building a course, where the learner needs to click on a graphic to reveal the content. And the revealed content stays put on the screen. It is okay to do this if I expect them to go in order - so when they click on 1 - the content for 1 appears, when they click on 2 - the content for 1 stays and content for 2 also appears and so on.
But how do I ensure the same is true if they click on 2 first? The way it is set up - when they click on 2 - content for both 1 and 2 is visible - even though they have not clicked on 1.
Can you help me sort this out please?
