It seems the only way to manage this at the moment is to create size and color as one option with the amount of stock i.e.
Red Small 5
Red Medium 7
Red Large 3
Red Extra Large 2
White Small 4
White Medium 2
White Large 5
White Extra Large 1
Which becomes very cumbersome if you have more than one color. If you have 5 colors, the options required are then 20 in a radio list or drop down and is very confusing for the customer to view.
The one option (e.g. size) should be conditional upon the other (e.g. color), a sub-option where the stock amount is entered, and not an entirely separate option for the stock to work properly, and the quantity should be entered only once in the sub-option part of this.
The separate options as they are at present are fine for non-stock options perhaps such as adding a gift wrap or service of some kind to the stockable item, or a sauce to a burger etc.
If it is not possible to set up a conditional option (as I mean above), perhaps creating proper child products under the main product would solve this, Giang? Where the child products are the color variations that have a total quantity on hand for each color, and the sizes are the options with stock quantity for each size?
