Campaign Mix and Match

Campaign Mix and Match has been added.

A new mix and match toggle has been added.

Toggle on "Allow Mix-And-Match"

There will be a new table at the bottom to set Mix and Match rules, and you can add rules by clicking the add button and delete by clicking the trash can button.

With Mix and match On, when you click Add Items to Campaign, it will allow you to add BOTH categories and products to this campaign (without this setting and with ApplyPriceByQuantity OFF, you can only add EITHER categories OR products)

It will look like this if you add both categories or products

You only need to add at least 1 product or category. Its not necessary to add both product or category.
However, there must be at least 1 row in Mix and Match rules.
If there are not enough products or mix and match rules, it should show error when you try to save:

If mix and match rules are not filled in, it will have error:
