zsh: show completion group names

Question

I'm writing some zsh completions and am stuck on how to have multiple groups of completions.

I added the group name with the -J parameter docs.

compadd -J group1 "$@" completion1 completion2
compadd -J group2 "$@" completion3 completion4

Then I added the zstyle to my ~/.zshrc docs (heading: group-name)

zstyle ':completion:*' group-name ''

The completions come up fine, but the group names are not being displayed. What am I doing wrong?

Answer 1

In my case the group names appeared only after adding:

zstyle ':completion:*' group-name ''
zstyle ':completion:*' format 'Completing %d'
