I have tried various options and only really have one solution that is close to my needs.
I tried the stockable plugin, but could not get the dropdowns to work (they kept appearing behind my addtocart existing section)
If you follow this link - http://elanvape.com/index.php/en/shop/liquids/eve-guava-e-liquid-detail
This is a 'Child Variant' with 3 children
The Children are selected using a custom field of 0mg, 6mg and 12mg
They all have different prices
The parent is NOT orderable, though I see no way of telling Virtuemart that
Choosing each variant does not update the price or stock availability
I can still order the parent
When I choose a different variant and try to order it, it still places the parent product (which is not orderable) into the cart.
So...I'm a little bit lost.
Only the generic child variant gives the frontend behavior I require, but offers no stock control.
Right now, I don;t have a working solution.
