WordPress Breadcrumb switch without plugin (hide show breadcrumb)

  breadcrumbs, php, wordpress

I’m looking for a button solution for breadcrumb.

I have a breadcrumb on the page that is under the header.

I would like to be able to turn it off / on on a given page / post.

I don’t want to use an extra plugin.

Page settings = show or hide breadcrumb. I saw this option somewhere but I can’t find the code.

Regards and thanks for help.
