I'm buiding a site for a company with a lot of products, and each product has a different set of technical data. I want to display the data in a definition list, like this (below the Tech spec heading). But the thing is I want to control the way the editors handle this. So what I need is a way to add one or several name-value pairs on the product pages, almost like building a table. The admin interface should probably look something like this.
What would be the best way to achieve this? Anyone that can point me in the right direction?
