Header and footer

The header, the announcement bar above it and the two footer sections are section groups: they appear on every page, and you edit them from any page in the theme editor.

Announcement bar

Sits above the header. Color scheme, Auto-rotate announcements, Change every (3–10 s).

Announcement blocks: Text and an optional Link. With two or more, the bar rotates and shows arrows; with one, it is simply a line of text.

Keep announcements short enough to fit a phone in one line. This is also the right place for the shipping promise that otherwise ends up in the hero.

Setting	Notes
Color scheme
Logo position (desktop)	Left or Center.
Menu	The navigation menu, from Content → Menus. Submenus become dropdowns; a third level becomes a nested list.
Sticky on scroll	The header stays at the top of the screen.
Transparent over the first section on the home page	White text and icons over your hero until the page scrolls. Best with a full-width hero or slideshow with no top padding.
Logo on transparent header	Optional, a light version of the logo for photographs.
Show search icon	Opens the search drawer with predictive results.
Customer account menu	Links shown in the account sheet. Appears when customer accounts are enabled.
Show cart icon

The account icon itself is Shopify’s own account component, so it always matches the customer accounts your store has turned on. It follows the theme’s colours and button shape automatically.

On phones the menu opens as a drawer, with submenus sliding in one level at a time.

Add a Mega menu block to the header for a full-width dropdown.

Each mega menu has a Menu item — the title of the top-level menu item it opens, for example “Shop”. The panel opens full width even when that item has no sub-links. Items without a mega menu open an ordinary dropdown.

Setting	Notes
Menu item	The top-level menu item’s title.
Menu columns per row	1–6. More columns wrap onto the next row.
Cards per row	1–6.
Cards layout	Grid — more cards wrap onto the next row. Carousel — the others scroll in with arrows or a swipe.

Then add blocks, in the order you want them. Menu columns sit on the left, cards on the right:

Block	Settings
Menu column	Heading, Heading link, Menu (only the menu’s top-level links are shown), Use the menu’s title as heading (when the heading is empty). Without any Menu column block, the menu item’s own sub-links are shown instead.
Promo tile	Image, Heading, Text, Link.
Collection card	Collection, Heading (defaults to the collection’s title), Show product count.
Product card	Product — shown with its image and price.

Add a second Mega menu block to give another top-level item its own panel.

Search drawer

Not a section you add — it is always there behind the search icon. Its own settings are Color scheme, Quick links (a menu shown under the field before anyone types, e.g. popular collections) and Quick links heading.

Predictive search returns matching products and suggested searches as the customer types.

The footer is two sections inside one landmark: Footer (the columns) and Footer bottom bar (the line underneath).

Color scheme and Column headings (Small capitals or Regular).

Blocks:

Block	Settings
Brand	Style: Logo (first column) or Large wordmark (full row). Logo (defaults to Theme settings → Branding; without a logo, the store name), Logo width, Name (defaults to the store name), Text.
Menu	Heading and a Menu. One block per column.
Text	Heading and Text — opening hours, a studio address, a note about lead times.
Newsletter	Heading, Text, Submit button (Text or Arrow), Button label.
Social	Heading. Shows the profiles from Theme settings → Social.

A single row of small blocks. Color scheme, Alignment (Left or Center), Show divider line above, Badge height.

Block	Settings
Copyright and policies	Show store policy links (written in Settings → Policies), Show “Powered by Shopify”.
Country and language	Style (Compact dropdown or Form with labels), Show country / currency selector (from Settings → Markets), Show language selector (from Settings → Languages).
Payment icons	Shows the payment methods turned on in Settings → Payments.
Follow on Shop	Lets customers follow your store in the Shop app. Shop Pay must be turned on.
Social	The profiles from Theme settings → Social.
Badge	Image, Link, Label — the label describes the image for screen readers and is shown as text when no image is set. For a certification, a trade body, or a national consumer-protection logo.
Menu	A menu’s top-level links in one line.
Link	A single Label and Link.
Spacer	Pushes the blocks after it to the right end of the bar. On phones it starts a new line.

The usual arrangement: Copyright and policies, then a Spacer, then Country and language and Payment icons.
