connection line grayed out in iBooks Author I went to menu-format-text and all that but the thing is the box grayed out totally.

At this point, all I could actually click on was the hide and show thing but of course I can't see anything really. [what is the hide and show thing]

I am not really good at handling Mac terminology and don't know where to start.
The option to connect boxes does not work with the title page.  Create two new boxes within the document, select both boxes using the Command Key then try connecting the boxes  again.
