Content creation

Hi.

It seems that some content types are not available for use in the Interactive Book, e.g. Image Choice.

Is there a way to somehow enbale them?

Hi. While creating an Interactive Book, i observed that not all content types are available to add in the book.

Is there a way to add the currently unavailable content types?

For example, i would like to use the "Image Choice" content type but it's unable for use within the Interactive Book even though i'm able to use it as a standalone content type.

I found on my page that the content (for example a word/button) on the top left and bottom is cutting off, not fully shown. It seems it has to do with the default margin thing. May I know how to fix this issue? Thanks millions for helping.
