Topic summary
Goal: Show a different header on specific pages in a Shopify store using the Dawn theme—such as swapping the logo or using an alternate menu; possibly also varying the footer.
Context: The store owner provided the site URL (almost-summer.com) and clarified they want page-specific header variations (logo/menu) on some pages.
Current status: No technical steps or code have been provided yet. A helper requested the URL to review before suggesting a solution.
Unresolved items: The exact method to implement page-specific headers in Dawn (Shopify’s theme) remains unspecified. There is no confirmation on whether this will involve theme settings, alternate templates, or custom code.
Next actions: Awaiting the helper’s review of the provided URL and a proposed approach. Discussion is open and unresolved; no decisions or implementations have been made yet.
