The Header inline (New) is a flexible element designed to display a title and optionally a short description inline with its own content, rather than as a separate, full-width section. Unlike the traditional Inline Header, the new version leverages theme blocks, offering greater flexibility and customization options for building diverse and dynamic menus.

The following guide will help you understand its structure and how to customize the Header inline (New) effectively.
1. How to access the Header inline (New) section?
Step 01: From Shopify Admin, click on Online Store > Select Themes > In the Current theme section, click the Customize button.

Step 02: In the theme editor (Customize), click the Sections button > In the Header group tab, click Add section botton > Scroll through the list or use the search bar to find and select the Header inline (New) section.

Note: Avoid using both the Inline Header and Inline Header (New) sections at the same time, as only one can be displayed. To ensure proper rendering, include just one of the two in your layout.
