Checkbox: "Allow the user to enter a css class"

silurius,

this is rather a support request and rather a request in general than specified for the link field module. Since such a need could occur also on other fields and since it is a very special need, I am not sure if link field should provide that by default, and I don't even think that it would make sense to create another general module for that to use it on any field.

Why? because it can be "build" with modules already there. Google is your friend. One example is shown here: http://stackoverflow.com/questions/5816174/drupal-options-of-css-classes...

But there are more out there.

Thanks for understanding

Changed wording a bit
