I'm new to Plone 5 and I'm actually following the plone training. However, I'm not used to the way that all is build. I would like to do simple things but I don't know where to start. For example:
How can I move the search bar from the header to the navbar menu?
How can I add an image to the header next to the logo?
Is there any tutorial that can help me?
Most of your questions can probably be answered with techniques from the official tutorials and documentation. See:
