Hey, I would like to have the possibility of having a admin field where you could add as many elements as you like (eg: via a ‘+’ button). For example: a reciepe model where the number of ingredients changes. Could someone help? thanks regardless 
Assuming you’re working with a properly designed data structure, (e.g. perhaps a Recipie model and a related Ingredients model), you’re looking for the InlineModelAdmin facilities.
It worked!!! thank you so much
