different colours for custom groups

[mihai-satmarean]

Hi, again we find it very useful to toy around, in order to see some production use we could have different groups represented with different colours. EG: Ansible reserved groups with grey and our defined groups with other colour, maybe even the children with specific colours. Thanks!

I'd suggest using a custom template (using the -t option) to achieve this. Other than all, there's not really any such thing as reserved groups, as far as I'm aware.

thanks! an example would be useful, I am not familiar with the format, just find it very nice how you do that

another question, dynamic inventory can be represented?
