@gremorie/ng-overlays

Overlay primitives for Angular: Dialog, AlertDialog, Sheet, Drawer, Popover, HoverCard, Tooltip, DropdownMenu, ContextMenu, Command and Sonner. A companion to Spartan-ng that fills the gaps for layered surfaces. Part of Gremorie, an AI native design system.

The React reference is @gremorie/rx-overlays; this package is built at parity with it. Behavior is delegated to @spartan-ng/brain primitives (CDK overlay based).

Full documentation lives at gremorie.com.

Install

npm i @gremorie/ng-overlays @gremorie/ng-core @spartan-ng/brain @angular/cdk

Requires Angular 21 (@angular/core ^21.2.0). The overlays share the Gremorie tokens through @gremorie/ng-core.

Styles

These primitives are styled with the Gremorie design tokens, so import the core theme once in your global styles.css:

@import 'tailwindcss';
@import '@gremorie/ng-core/theme.css';

Usage

Brain overlays render their content from a <ng-template> referenced by the trigger — the documented divergence from Radix's portal model. For Dialog:

import { Component } from '@angular/core';
import {
  Dialog,
  DialogTrigger,
  DialogContent,
  DialogHeader,
  DialogTitle,
  DialogDescription,
  DialogFooter,
  DialogClose,
} from '@gremorie/ng-overlays';

@Component({
  selector: 'app-example',
  standalone: true,
  imports: [
    Dialog,
    DialogTrigger,
    DialogContent,
    DialogHeader,
    DialogTitle,
    DialogDescription,
    DialogFooter,
    DialogClose,
  ],
  template: `
    <gr-dialog #dialog>
      <button [grDialogTriggerFor]="dialog">Open</button>
      <ng-template grDialogContent>
        <gr-dialog-content>
          <gr-dialog-header>
            <gr-dialog-title>Edit profile</gr-dialog-title>
            <gr-dialog-description>Make changes here.</gr-dialog-description>
          </gr-dialog-header>
        </gr-dialog-content>
      </ng-template>
    </gr-dialog>
  `,
})
export class ExampleComponent {}

Components

• Dialog / AlertDialog / Sheet / Drawer — modal surfaces on the brain dialog primitive (Drawer is a bottom-anchored Sheet variant since there is no Angular vaul).
• Popover / HoverCard / Tooltip — anchored overlays.
• DropdownMenu / ContextMenu — action menus built on the brain popover (brain ships no menu primitive).
• Command — keyboard-first palette on the brain command primitive.
• Sonner (Toaster + toast) — transient toasts on the brain sonner primitive.
