Currently I understand the system of templates as follows:
[depends layouts] (page_layout) ↓ layout (page_layout) ↓ magento default.xml (page_configuration) ↓ my theme default.xml (page_configuration) ↓ module file super-module-file.xml (page_configuration) ↓ = merge.
I have a 2 layout:
wide_page. I want to change block "header-wrapper" depending of the layout. But currently
default.xml (in magento/theme) overrides this block. I can not use my
default.xml because next time this file apply for both layouts.
How I can solve this problem?
