Scenario: a custom content block in my header. The content comes from a "Page". (I didn't use a "post" because I didn't want this content to be part of the blog archive call-ups.)
I have a social media plugin and it puts the social media buttons in the custom content block, but I'd like to say "but not this one". I assume that I need to write up a function or a filter to do this. Can someone point me to a couple specific examples of this being done, or to codex pages that can help me?
Thanks!
