Usage

import { HlmDrawerImports } from '@spartan-ng/helm/drawer';

<hlm-drawer>
  <button hlmDrawerTrigger hlmBtn variant="outline">Open</button>
  <hlm-drawer-content *hlmDrawerPortal="let ctx">
    <hlm-drawer-header>
      <h3 hlmDrawerTitle>Are you absolutely sure?</h3>
      <p hlmDrawerDescription>This action cannot be undone.</p>
    </hlm-drawer-header>
  </hlm-drawer-content>
</hlm-drawer>

Examples

Direction

You can change the direction the drawer slides in from using the direction input on the trigger.

import { ChangeDetectionStrategy, Component } from '@angular/core';
import { HlmButtonImports } from '@spartan-ng/helm/button';
import { HlmDrawerImports } from '@spartan-ng/helm/drawer';

@Component({
	selector: 'spartan-drawer-direction-preview',
	imports: [HlmDrawerImports, HlmButtonImports],
	changeDetection: ChangeDetectionStrategy.OnPush,
	template: `
		<hlm-drawer>
			<div class="flex flex-wrap gap-2">
				<button id="bottom" hlmDrawerTrigger direction="bottom" hlmBtn variant="outline">Bottom</button>
				<button id="top" hlmDrawerTrigger direction="top" hlmBtn variant="outline">Top</button>
				<button id="left" hlmDrawerTrigger direction="left" hlmBtn variant="outline">Left</button>
				<button id="right" hlmDrawerTrigger direction="right" hlmBtn variant="outline">Right</button>
			</div>
			<hlm-drawer-content *hlmDrawerPortal="let ctx">
				<hlm-drawer-header>
					<h3 hlmDrawerTitle>Edit profile</h3>
					<p hlmDrawerDescription>Make changes to your profile here. Click save when you're done.</p>
				</hlm-drawer-header>
				<div class="px-4">
					@for (item of _items; track item) {
						<p class="mb-4 leading-normal">
							Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod tempor incididunt ut labore et
							dolore magna aliqua.
						</p>
					}
				</div>
				<hlm-drawer-footer>
					<button hlmBtn>Save changes</button>
					<button hlmBtn variant="outline" hlmDrawerClose>Cancel</button>
				</hlm-drawer-footer>
			</hlm-drawer-content>
		</hlm-drawer>
	`,
})
export class DrawerDirectionPreview {
	protected readonly _items = Array.from({ length: 3 }, (_, i) => i + 1);
}

Nested

Drawers can be nested within each other to create multi-step or drill-down experiences. Use a nested hlm-drawer inside the content of another drawer.

import { ChangeDetectionStrategy, Component } from '@angular/core';
import { HlmButtonImports } from '@spartan-ng/helm/button';
import { HlmDrawerImports } from '@spartan-ng/helm/drawer';

@Component({
	selector: 'spartan-drawer-nested-preview',
	imports: [HlmDrawerImports, HlmButtonImports],
	changeDetection: ChangeDetectionStrategy.OnPush,
	template: `
		<hlm-drawer>
			<button hlmDrawerTrigger hlmBtn variant="outline">Open Drawer</button>
			<hlm-drawer-content *hlmDrawerPortal="let ctx">
				<hlm-drawer-header>
					<h3 hlmDrawerTitle>Profile Settings</h3>
					<p hlmDrawerDescription>Manage your account settings.</p>
				</hlm-drawer-header>
				<div class="px-4">
					<p class="mb-4 leading-normal">This is the first drawer. You can open another drawer on top of this one.</p>
					<hlm-drawer>
						<button hlmDrawerTrigger hlmBtn variant="outline">Open Nested</button>
						<hlm-drawer-content *hlmDrawerPortal="let nestedCtx">
							<hlm-drawer-header>
								<h3 hlmDrawerTitle>Nested Drawer</h3>
								<p hlmDrawerDescription>This drawer is nested inside the first one.</p>
							</hlm-drawer-header>
							<div class="px-4">
								<p class="mb-4 leading-normal">Nested drawers allow you to layer content without losing context.</p>
							</div>
							<hlm-drawer-footer>
								<button hlmDrawerClose hlmBtn variant="outline">Close</button>
							</hlm-drawer-footer>
						</hlm-drawer-content>
					</hlm-drawer>
				</div>
				<hlm-drawer-footer>
					<button hlmDrawerClose hlmBtn variant="outline">Close</button>
				</hlm-drawer-footer>
