Hi,
I would like to enable two seperate editors one for introtext and one for full text.
I would be very thankful f someone can give advice how to do this.

Go to K2 and click Parameters from the top menu. Then navigate through the Advanced tab and enable it through there. The option is "Use one editor window for introtext & fulltext".

So when I set "Use one editor window for introtext & fulltext" to no I will get two separate editors - one for introtext and one for full text?

If that is the case then how will I edit intro text separately?

Yes. When you set this option to No, when you edit the K2 item you will have 2 different content boxes. The first one will be for the intro text and the second one for the full text.

Thank you.
