Hi, the form you need to create must work like this:
- you need to create a new menu item in Catalog called "Products Ordering"
- Entering must ask if it is an Attribute or Function
- Selecting example Function must display existing Functions
- Selecting a Function must show the values inside the vation and you must give the possibility to position the functions as you wish.
- On the Front-end the result must be to see the list of products in order of the values of the Function
