What its author says it does

Copied from the file, not written here

Quick global settings — currency, language, region, units — belong in a persistent, low-profile location such as a header toolbar or footer. These controls are frequent but not primary, so they use small typography and stay out of the main content hierarchy. Use when designing global selectors, locale switchers, or user preference controls that apply across the whole product.

Global Toolbar Controls

What Belongs Here

Global controls affect the entire product experience but are not the user's primary task. They are reached occasionally — once per session or less — and should not compete visually with primary navigation or content.

Typical global toolbar controls:

Currency selector (e-commerce, financial tools)
Language / locale switcher
Region or market selector
Unit system (metric / imperial)
Theme toggle (light / dark)
Accessibility preferences (font size, contrast)

These are distinct from user account settings (which live in a profile menu) and from contextual settings (which live adjacent to the feature they affect).

Where to Place Them

Header utility strip

A secondary row above or within the main header, right-aligned. Common on e-commerce and international sites.

[Logo]                    [EN | EUR | 🌍]  [Account]  [Cart]
────────────────────────────────────────────────────────────
[Main navigation]

Header right — compact

Inline with the main header, far right, using small typography and minimal visual weight.

[Logo]  [Nav items ...]              [EUR ▾]  [EN ▾]  [Account ▾]

Footer

For controls the user sets once and rarely revisits. Language and region selectors frequently appear in footers on large international sites (Airbnb, Apple). Appropriate when the control is truly infrequent.

Dedicated settings area

For more complex preference sets, a Settings page or panel is cleaner than cramming everything into the toolbar. The toolbar should link to it, not contain it.

Typography and Visual Treatment

Global toolbar controls are secondary UI — they should not draw the eye away from primary content.

Font size: 13–14px — deliberately smaller than body text (14px maximum per the type scale)
Colour: muted — use a secondary text colour (--color-text-secondary), not the primary text colour
No bold — regular weight only
Compact spacing — tighter padding than primary navigation items
Separator — a | or thin vertical rule between adjacent controls (language | currency) keeps them grouped without using full button chrome

.toolbar-control {
  font-size: var(--text-sm);       /* 13–14px */
  color: var(--color-text-secondary);
  font-weight: 400;
  padding: 4px 8px;
}

Interaction Pattern

Global controls typically use a compact dropdown — clicking the label opens a small popover or select with the available options.

Show the current value as the trigger label: EUR ▾, EN ▾
Use a flag icon + language code for locale, or currency symbol + code for currency
Keep the option list short — if it exceeds ~20 items, add a search input inside the dropdown
On selection, apply immediately and confirm with a brief status update (toast or inline update) if the change has a visible effect

Review Checklist

Are global controls placed consistently in one location across all pages?
Is the typography smaller and more muted than primary navigation?
Does the control show the current value as its label?
Is the dropdown or popover compact and keyboard-navigable?
Are global controls separated from user account settings?
On mobile, are global controls accessible without being prominent? (Often moved to a menu or footer on small screens)
