Hi,
Also, in case you want to edit the header section, we have some header styles in Theme Options and you can select one of them for your site.
Each header style will have its own configuration.
If you are asking how to edit the header with the Elementor template, it's impossible because this is not a page. No one can edit the header like a page. Hope you understand this.
If you want to config the header, pls provide the admin and let me know your intention. We will help you to check it and give you the correct answer. Thank you!
