Hey guys,
I am new to this community because I have a problem with K2 attachements.
Thanks for helping me in advance :)

I would like to have a linebreak after every attachement of a K2 article.
How is it possible to implement this and if not, is there a possibility to at least number them?

best regards :)

How does the attachments display at the moment on your site?

The attachments are displayed as lists by default <ul> . If you want numbering, then you can do a template override and then change the attachments code block in the item.php file to use <ol> instead of the <ul>

Remember to use overrides so you won't lose your edits when you update.
More information on overrides can be found here: getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates
