CE.SDK provides the ly.img.assetLibrary.dock component for adding buttons to the dock that open the asset library panel. This is the fastest way to give users access to specific asset categories without registering custom components.

This guide covers adding single dock buttons, combining multiple asset categories, configuring button appearance, adding custom click handlers, and organizing buttons with separators and spacers.

Add a Single Dock Button#

Use insertOrderComponent() with the asset library dock component and inline configuration to add a button to the dock. The entries array specifies which asset library entries open when the button is clicked.

// Add a Media button combining images and videos
cesdk.ui.insertOrderComponent(
  { in: 'ly.img.dock' },
  {
    id: 'ly.img.assetLibrary.dock',
    key: 'media',
    entries: ['ly.img.image', 'ly.img.video'],
    label: 'Media',
    icon: '@imgly/Image'
  }
);

When clicked, this button opens the asset library panel showing both images and videos. The key property must be unique when using multiple dock buttons with the same component ID.

Configure Button Appearance#

The ly.img.assetLibrary.dock component accepts these configuration properties:

Property	Type	Description
`id`	`string`	Must be `'ly.img.assetLibrary.dock'`
`key`	`string`	Unique identifier (required when using multiple dock buttons)
`entries`	`string[]`	Asset library entry IDs to show when clicked
`label`	`string`	Button text label (supports i18n keys)
`icon`	`string`	Icon identifier (e.g., `'@imgly/Image'`, `'@imgly/Shapes'`)
`onClick`	`() => void`	Custom click handler (overrides default panel behavior)
`selected`	`boolean`	Override the selected state
`disabled`	`boolean`	Whether button is disabled
`size`	`'normal' \| 'large'`	Button size
`variant`	`'regular' \| 'plain'`	Button style variant
`color`	`string`	Button color

// Add an Elements button for shapes and stickers
cesdk.ui.insertOrderComponent(
  { in: 'ly.img.dock' },
  {
    id: 'ly.img.assetLibrary.dock',
    key: 'elements',
    entries: ['ly.img.sticker', 'ly.img.vectorpath'],
    label: 'Elements',
    icon: '@imgly/Shapes'
  }
);

This example adds an Elements button that opens shapes and stickers when clicked.

Add a Custom Click Handler#

Override the default panel-opening behavior with a custom action using the onClick property. This is useful when you want a dock button to trigger custom functionality instead of opening the asset library.

// Add an Upload button with custom onClick handler
cesdk.ui.insertOrderComponent({ in: 'ly.img.dock' }, [
  'ly.img.spacer', // Push upload to bottom
  {
    id: 'ly.img.assetLibrary.dock',
    key: 'upload',
    entries: ['ly.img.upload'],
    label: 'Upload',
    icon: '@imgly/Upload',
    onClick: () => {
      // Custom behavior instead of opening asset library
      console.log('Custom upload action triggered!');
      // In production: open your custom upload dialog
      alert('Custom upload dialog would open here!');
    }
  }
]);

The onClick handler completely replaces the default behavior. In this example, clicking Upload triggers a custom dialog instead of opening the asset library panel. The ly.img.spacer component pushes the Upload button to the bottom of the dock.

Built-in Asset Entry IDs#

Common asset library entry identifiers to use in the entries array:

Entry ID	Description
`ly.img.image`	Image assets
`ly.img.video`	Video assets
`ly.img.audio`	Audio assets
`ly.img.text`	Text presets
`ly.img.vectorpath`	Shape assets
`ly.img.sticker`	Sticker assets
`ly.img.template`	Templates
`ly.img.upload`	Upload functionality

Using Separators and Spacers#

Organize dock buttons with visual separators and flexible spacers.

// Insert a separator between Elements and Text
cesdk.ui.insertOrderComponent(
  { in: 'ly.img.dock', after: { key: 'elements' } },
  'ly.img.separator'
);

You can insert separators between existing components using positional matchers like after: { key: 'elements' }.

Separator rendering rules:

Adjacent separators collapse to one
Separators at dock edges are hidden
Separators above a spacer are hidden

Positioning Dock Buttons#

Control where dock buttons are inserted using positional matchers.

// Insert a button at the beginning of the dock
cesdk.ui.insertOrderComponent(
  { in: 'ly.img.dock', position: 'start' },
  {
    id: 'ly.img.assetLibrary.dock',
    key: 'templates',
    entries: ['ly.img.template'],
    label: 'Templates',
    icon: '@imgly/Template'
  }
);

The before and after options accept 'first', 'last', or a matcher object. Matcher objects can target components by key or id. See the Component Order API for all available matcher options.

Available Icons#

Common icon identifiers for dock buttons:

@imgly/Image - Images/photos
@imgly/Camera - Camera/capture
@imgly/Video - Video content
@imgly/Audio - Audio/music
@imgly/Text - Text/typography
@imgly/Shapes - Shapes/elements
@imgly/Sticker - Stickers
@imgly/Upload - Upload
@imgly/Template - Templates

Troubleshooting#

Button not appearing - Verify the asset source exists for the entry IDs. Buttons only show if matching sources are registered.

Duplicate keys error - Ensure each ly.img.assetLibrary.dock instance has a unique key.

Icon not showing - Verify icon identifier is correct (case-sensitive).

Wrong panel opening - Check that entries array contains the correct asset source IDs.

onClick not firing - Check that the function is defined and not throwing errors.

API Reference#

Method	Purpose
`cesdk.ui.insertOrderComponent()`	Insert dock buttons into the dock
`cesdk.ui.removeOrderComponent()`	Remove dock buttons
