With my inherent naivety, I want to ask habrausers who are familiar with Drupal for help.
There is such a type of text field in Drupal when asked to enter values via \ n. In addition, there is a field - radio button. In addition, Drupal has such a wonderful setting - Ubercard. Actually what I want.
When adding a product, values are entered in such a text field through \ n, and then, on the product card, the user can select one of these values. If someone has an idea how to do it - I will be extremely grateful.
