In my webshop I'm using a custom product configurator that pushes data into the product fields. I added read more/less code and functionality into the long description, it works great in the cart until I go to the backend and press "Save" on the product. The entire HTML breaks and the read more/less stop working.
Someone told me it might be Shopware's HTML sanitizing in the backend, does anyone know if this is the issue and if so, what the solution here could be.
Thanks a lot!
