Create my own menu
Can somebody help me about how to create my own menu.
I created a slide with a menu. And the idea is to click on the button to access to the chapter.
So there is 4 chapter in my menu.
I want the 3 last chapter "disabled" (so that the user can't click on these 3 last buttons) until all the 1st chapter is read.
At the last slide of the 1st chapter, when the user click on the "next" button, he'll arrive on the menu slide and the 2nd chapter will be "normal" (so that the user can click on this button).
I hope that you understood my question and somebody can help me.
