I'm trying to work out how to add textfield to the navbar in the header that I can use as an always present search box but I haven't had much success. From the documentation (7.2. Replacing page elements) I see that I can replace components inside a page but I don't think this applies to the header. Can any one point me in the right direction with where to start with this?
It is possible to change the complete header by using ComponentType.HEADER.
Setup your own ComponentFactory that will have higher priority than the default one.
