Header

Header settings in Theme settings > Header control how the header behaves while customers scroll and whether top sections can render under the header when overlap is enabled at the theme and section level.

Default desktop header

In Slab 0.5.0, the default desktop header uses a text Search control to the left of the logo.

How to change theme header

Choose header position

Open Theme settings > Header.
Under Position, choose Sticky, Standard, or Dynamic.
Preview desktop and mobile before changing overlap.

Configure overlap

Turn on Enable header overlap only when top sections are designed for content under the header.
Set Desktop overlap and Mobile overlap when overlap is enabled.

Enable overlap on sections

Open each section that should sit under the header.
Turn on that section’s Enable header overlap setting.
If either the theme-level or section-level overlap setting is off, the section stays in normal flow.

Notes on header behavior

Sticky keeps the header visible while scrolling; Standard scrolls with the page; Dynamic can hide the header while scrolling down and show it when scrolling up—preview your main templates.
Overlap values use 5 px steps from 5 to 200 px; tune them to your logo and bar height.
