Create an interactive cookbook
Hello People,
I'm a beginner in ibooks author and I'd like to create an interactive cookbook (already all written, in French).
1) What I'd like to create is that inside of each recipe, one can enter the number of people, and this produces the ingredient quantities to be adapted in the ingredient zone of the corresponding recipe.
The way I imagine would be that I pre-enter the results in a hidden part of the ibook (is it possible?), and according to the number of people typed by the reader for the recipe, the right quantities appear from the hidden part in the ingredients' column (another way would be to apply a mathematic formula, but for certain products like spices, the quantities are not exactly proportional to the quantity of people, at least for small number...)
What would be a way to create these possibilities?
2) How to obtain a Buying List that could be edited or printed, built from the ingredients of the recipes the reader decides to cook and the number of people he entered before ?
3) I'd like to add the possiblity for the reader, inside of the buying list to be edited, to erase manually some ingredients in case he(she) already has it ?
I thank you very much in advance for providing me solutions and for your time !
