We've already had a similar request, but it may be obscure for your searches since it was not in English.
Ecwid currently implies, that you keep such things in the product description, but it is still possible to display these parameters in the grey block on the right of each product page, near the price via a hack. Here it is:
1. Add your parameters to the product as
product options of type "Radio Buttons". The name of the attribute (like "Author") goes to the name of the option group, and the value goes as the only available option.
2. Hide the radio buttons in the storefront, so that they do not appear as real options that the customer must fill prior to buying. To do that add the following code to your
ecwid css theme
Code:
.ecwid-productBrowser-details-optionPanel .gwt-RadioButton input {
display: none;
}
The downside of this hack is that it hides all the radio button options - so you will have to use Dropdown type of options where you expect a selection from your customer.
