Available content types in Interactive Book

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.

Hi shrey42,

Not all content types can be created in Interactive Book, for these content types to be added the code needs to be edited.

Hi BV, thanks for your response.

Could you kindly guide me towards any documentation using which i can edit the code to include these content types?

Thanks
