I’ve add a css below to make these variables are out of stock or disabled.
.single-product-content .variations .swatches-select .swatch-disabled {
display:none;
}
The problem is the ajax are not function while the products page open, it’s have to click the swatches options (ex: color / size) then the disable options will disappear.
Could the ajax are function while the products page open instead click the swatches options to make it disappear.
My english isn’t well to describe, please visit my product page with disabled swatches option.
