I have a custom taxonomy which I want to behave in the same way that tags do on the post edit screen, instead of how categories appear. I have tried passing in the 'show_tagcloud' => true attribute, but it is still behaving like categories.

  • What does "it behaving like categories not tags" mean?

  • Also, those two links are unreleated to this question - they specify adding the built-in tags taxonomy to a custom post type, where as this question refers to making a custom taxonomy behave similar to the built-in tags taxonomy.
