Magento 2.1 - How can I remove the ability for a user to UNSELECT a swatch image?
I have all configurable products, I have created default simple product configurations for all configurable products. In the configurable product I have a double swatch configuration and if the user accidentally clicks twice on a swatch image, that option becomes UNSELECTED. I need to remove the ability for the user to UNSELECT any swatch, the configurable product must always have a swatch selected. The user can choose different configurations, and move about, but should never be allowed to select nothing.
I have configured default configurations on all configurable products and I want the swatches to behave like radio buttons in that the user always has 1 of each selected. We have a total of 2 possible swatches. FRAME color and LENS color; one of each must always be selected.
