It uses the ‘dflip’ shortcode to fetch the book(s) by their ID(s) or category. If ‘all’ or ‘*’ is used, it fetches all the books. The ‘limit’ attribute restricts the number of books displayed. The output is a neatly styled div containing your 3D flipbooks.

Examples and Usage

[dflip books="1,2,3" limit="2" /]
