Shortcode exclude category

Question

How can I exclude only one category from my homepage?

This is one shortcode that I'm using to show the newest posts

[vc_row][vc_column][td_block_big_grid category_id="22" sort="newest_posts"][/vc_column][/vc_row]

But it shows even the posts I don't want them to be there.

Answer 1

FOUND solution:

What I did was to add on category_id the negative number of the category. For example, I had category_id="22" and then, added another category category_id="22, 23" and both categories showed up.

After, I changed it to category_id="-22, 23" which made the posts from category 22 to not show up.
