Feature Header

Content header

Show the active tab's title (and subtitle) as a heading strip above the card content — handy when the tab labels are small or icon-only.

Config key: header (top-level boolean) · Default: false

type: custom:tabdeck-card
header: true
tabs:
  - name: Climate
    subtitle: Living room · 3 zones
    icon: mdi:thermostat
    card: { ... }

Notes

• The header updates as you switch tabs, showing the current tab's name and subtitle.
• Pairs nicely with tab_display: icon — a compact icon bar plus a clear title above the content.

Want an icon rail instead?

A narrow vertical icon rail is just position: left + tab_display: icon:

type: custom:tabdeck-card
