Is it possible to deploy only a folder of a repo ?

[pegros]

In my repositories, I often have more than one folders, e.g.:

• one main folder containing the core components of the package
• an example folder with configuration / code samples
• an extension folder e.g. with a CRM Analytics application

Currently, I have to clone the complete repo (with all folders) into separate branches (e.g. with only the main folder) to offer users the ability to choose between deploying the whole or only the core part of my repos.
You may see my PEG_SYS repo as an example.

Is there a way to achieve this (I do not think I may leverage github tags for this) ?
Thanks in advance for your help.
