Original questions asked by a member of the community Friederike Heinze on the #sxa Slack channel.
I would like to add an image field to the Link component. The additional rendering of the image field is no problem thanks to the rendering variants. But if I want to add a template field Image to the datasource item, I have to clone the whole rendering, because I am not allowed to edit the default SXA templates.
What is the proper way to extend existing component data sources without modifying the original template?
