subpanel add

A subpanel is a webview view rendered inline inside a menu’s activity-bar container (unlike a panel, which opens in the editor area).

vsceasy subpanel add --name history --menu settings --title "History"

Flags

Flag	Type	Notes
--name	text	Required. Subpanel id.
--menu	menu id	Required. Container to render inside.
--title	text	View title.
--withApi	yes | no	Generate a typed RPC interface.

What it generates

• src/subpanels/<name>.ts — the subpanel definition.
• src/webview/subpanels/<name>/{App.tsx,main.tsx} — the React UI.
• Appends <Name>ViewApi to src/shared/api.ts when the API is on.

src/subpanels/history.ts

import { defineSubpanel } from '../shared/vsceasy';

export default defineSubpanel({
  title: 'History',
  menu: 'settings',
  order: 2,                                     // position inside the container
  titleActions: [{ command: 'clearHistory' }],  // buttons on the title row
});

Subpanels and panels share the same RPC machinery — see Typed RPC.

Subpanels and tree views share one ordering inside a container, so a tree view with order: 1 sits above a subpanel with order: 2. See Sidebar views.
