Hello.
Form the example you have provided, you can create the same products in this way:
1) You need to create configurable attributes. In example there is only selection of color, so you need to create 'Color' attribute.
Make sure you have made it configurable setting:
- scope - global
- input type - drop-down
- assigned to simple and configurable products
- used to create configurable products- yes
- added values for color attribute - Charcoal and Berry
2) Create product of configurable type, select attribute set where you added your Color attribute and select Color as configurable attribute (your future drop-down). Let;s call it Yoga Shorts
Then fill in all the required fields.
3) Create associated simple products and assign them to parent configurable.
Now you need to create variations. In example only 2 colors so there will be 2 variations - Charcoal Shorts and Berry shorts.
If you for example had 2 colors and 3 sizes you would have to create 6 variations: Charcoal Shorts S, Charcoal Shorts L, Charcoal Shorts M, Berry shorts S, Berry shorts M, Berry shorts L.
You can use quick creation form for this -
This way you will have: 1 configurable product Yoga Shorts where client will have drop-down to select necessary color and 2 separate simple products - Charcoal Shorts and Berry Shorts (you have to put visibility - catalog, search for simple products as well).
Here is article with detailed tutorial on configurable product creation -
Hope this helps.
