I am using Magento 2, I have some Configurable Products with a lot of variants (in some cases there are 5 attributes, each with several options). Each variant has a Simple Product associated with it, and the prices are set up under the Super Product Attribute Configuration.
Everything looks correct in Admin as far as I can tell.
On the Front end product page, the first time you select your options is fine, some options are disabled (greyed out) based on the choices you select. (For example, a certain Size may not be available in a certain Colour and that Colour may not be available for one if the other choices etc)
However, if you then change your mind, and what to select a different combination of options, you can't do this because some options remain disabled.
Currently, if I want to change the option value but that value can't be changed as I attached a screenshot so can anybody help? how to do without refreshing page?
