[BZ#777015] Find ingredients by type
Submitted by Michael Moroni
Link to original bug (#777015)
Description
By now a list of ingredients is shown in the "Ingredients" section. It can be useful a search by type: some ingredients will be subclass of more general class of food.
Example: I'd like to find all recipes with legumes. Then I look for the "Legumes" class, which is a subclass of Plants and I find all recipes with legumes (peas, chickpeas, beans, ...)
This supposes that ingredients are pre-defined, with a hierarchical structure behind, instead of just plain text.
