If you simply insert the link, Shopware will automatically give the link a NOFOLLOW attribute. Idealo has asked me to remove this, as this is understandably not in accordance with the agreement. Just add the link without http:// and it will work.

So that you don’t have to search for the right text module forever, it is recommended to simply enter the word “Hotline” in the search field.
