Subheader Patterns

Intended for use at the top of pages, but below the Page Header, the following component combinations serve as recommended patterns for composing subheaders.

Standard

Use for main page subheaders with breadcrumb, page title, and action buttons in a clean two-row layout.

Stacked Metadata

Main page subheader with key-value metadata row stacked below the title. Ideal for displaying session details, status badges, and entity relationships.

Inline Metadata

Use for main page subheaders with metadata columns inline beside the title. Uses vertical divider to separate metadata from action buttons.

Tabs

Use for main page subheaders with tabbed navigation below the title. Uses custom padding to align tabs flush with panel edges.

Kitchen Sink, Stacked

Feature-rich main page subheader with back navigation, stacked metadata row, and tabbed navigation. Alternative to inline layout for data-heavy contexts.

Kitchen Sink, Inline

Use for feature-rich main page subheaders combining back navigation, inline metadata, divider, and tabbed navigation at max complexity.

Detail Page Headers

Detail pages are one level deeper in the navigation and should use <nve-card container="full"> containing a "back" icon button preceding the page title.

Standard

Detail page subheader with back arrow navigation, multi-level breadcrumb, and minimal action buttons. Use for drilling into specific records.

Stacked Metadata

Use for detail page subheaders with a stacked metadata row showing entity attributes as key-value pairs horizontally below the title.

Inline Metadata

Use for detail page subheaders with inline metadata columns beside the title. Uses vertical divider to visually separate metadata from action buttons.

Tabs

Detail page subheader with back navigation and tabbed content sections. Ideal for entity detail views with many data categories.

Kitchen Sink, Stacked

Use for comprehensive detail page subheaders with stacked metadata row and tabs. Ideal for better vertical organization when metadata items are many.

Kitchen Sink, Inline

Use for comprehensive detail page subheaders with inline metadata, divider, and tabs. Ideal for complex entity views needing max feature density.
