| Guidance | Practices |
|---|---|
| Do | Include a product logo and name in the heading slot to clearly identify the application. |
| Do | Limit primary navigation items to 5 or fewer for quick scanning and minimal cognitive load. |
| Don't | Avoid using TopNav to filter page content — use Tabs or filter controls instead. |
| Don't | Avoid deeply nested navigation hierarchies — keep menus to one level of depth. |
| Prop | Type | Description |
|---|---|---|
heading | ReactNode | Heading slot content (logo, brand) — positioned at the left edge of the nav bar. |
startContent | ReactNode | Start content slot for navigation items or breadcrumbs — positioned after the heading, left-aligned. |
centerContent | ReactNode | Center content slot (tabs, search bar, primary navigation) — when provided, switches the layout to a three-column CSS grid for true horizontal centering. |
endContent | ReactNode | End content slot for search, icons, or user profile — positioned at the right edge. |
label | string | Accessible label for the navigation landmark, applied as aria-label on the <nav> element. |
xstyle | StyleXStyles | StyleX styles for layout customization (margins, positioning, sizing). Must be a stylex.create() value — not an inline style object like style={{}}. |
| Prop | Type | Description |
|---|---|---|
heading | string | Heading text to display. |
logo | ReactNode | Logo element to display before the heading text. Can be an image, XDSNavIcon, or any ReactNode. |
href | string | URL to navigate to when clicked. When provided, renders as an anchor element. |
| Prop | Type | Description |
|---|---|---|
labelrequired | string | Accessible label for the nav item. Rendered as visible text by default. When isIconOnly is true, used as aria-label instead. |
href | string | Navigation target URL. |
isSelected | boolean (default: false) | Whether this nav item is currently selected. Sets aria-current="page" and applies highlighted styles. |
isDisabled | boolean (default: false) | Whether the nav item is disabled. Sets aria-disabled and prevents interaction. |
isIconOnly | boolean (default: false) | Renders the item as a square icon-only element. When true, label becomes the aria-label and visible text is hidden. Requires icon to be set. |
icon | ReactNode | Optional icon to display before the label. |
children | ReactNode | Custom content to render instead of the label text. |
as | XDSLinkComponentType | Custom component to render instead of <a>. Overrides the provider-level default set by XDSLinkProvider. Must accept href, className, style, and children props. |

delay | number (default: 150) | Delay in milliseconds before showing the menu on hover. |
hideDelay | number (default: 250) | Delay in milliseconds before hiding the menu after the mouse leaves. |
