I have created an extra field for each option (text field, multi selection, radio button, link and text area), assigned to an extra field group.
Then assigned the field group into a category and created an article in that category, only the text field shows up under additional information but none of the other extra fields show on the article.
The show extra field in category view option and item view option are both selected as show.
I am using the latest version of joomla and of K2.

Could anyone help ?
