How to hide ‘link categories’?

If you just have one link category, you could use wp_get_links() to display the links from it (it does not provides a “category” heading):

EDIT: Forgot get_links() does the same for all categories:

I am very greatful, really. I could find a perfect & simple solution for the problem.

I changed the wordpres classic theme
<?php get_links_list(); ?>

to this:
<?php wp_get_links(1); ?>
– That means it only displays links from the first category and it does not show the name of the category.

That’s all.
