While we are making a Wish List around Combinations, I would like to be able to use multiple Items with Combinations to make a Product Pack. PS 1.5 documentation states: "You cannot currently add combinations ... to a pack ... This is a known limitation that will be fixed in a coming version of PrestaShop." Yes there are PS modules out there to do this, notably Advanced Pack 5 - by Presta-Module for $249 US.
But maybe thirty bees will incorporate this limitation into the core someday.
The way that my shop needs to use it is as follows:
We sell a bed and it comes in five different sizes: Twin, Full, Queen, King, California King, two different woods: Oak, Maple and is available in different colors: Unfinished, Standard Finish, and Custom Finish. Complicating this matter is that the Manufacturer sells the beds in three component parts: Headboard, Footboard, and Rails.
I would create the three component parts of headboard, footboard and rails, each with attributes of size, wood, and color.
Then ideally we will be able to offer "Jamestown Beds" on 1 product page and allow the customer to select the size, wood, and color for each of the three components (headboard, footbboard, rails) and the price would be calculated on the fly.
This state of being would be called Nirvana :-)
