I am using an extension of the mageworx "Advanced Configurable Option ..." https://www.mageworx.com/magento-2-advanced-product-options-suite.html
I could have used the basic magento configurable products, but unfortunately for the work I had to do I should have created more than a thousand attributes.
The extension support told me that it is an incompatibility with my theme, and I have to pay. But I like to solve problems alone and above all to understand how I solved it well. This is to enrich my experience.
"isWatched" It should hide the dropdown , but in my theme it doesn't work and the drop down remains.
