Note:

Asset selector was called Asset picker in prior versions of AEM.

The asset selector lets you browse, search, and filter assets within Adobe Experience Manager (AEM) Assets. You can also fetch the metadata of assets that you select using the asset selector. To customize the asset selector interface, you can launch it with supported request parameters. These parameters set the context of the asset selector for a particular scenario. You can pass the request parameters selection mode (single or multiple selections), or viewmode (to launch asset selector in search mode) with assettype (image, video, text) and mimetype as contextual information for the asset selector, which remains intact throughout the selection. 

The asset selector uses the HTML5 Window.postMessage message to send data for the selected asset to the recipient. 

The asset selector is based on Granite's foundation picker vocabulary. By default, the asset selector operates in browse mode. However, you can apply filters using the Omni search experience to refine your search for particular assets.

Any web page (irrespective of whether it is part of the CQ container) can integrate the asset selector by accessing it through the URL http://<host>:<port>/aem/assetpicker.html.

Contextual Parameters

You can pass the following request parameters in a URL to launch the asset selector in a particular context:

Name

Values

Example

Purpose

Folder path as the resource suffix in the URL:

http://localhost:4502/aem/assetpicker.html/<folder_path>

To launch the asset selector with a particular folder selected, for example with the folder /content/dam/we-retail/en/activities, selected, the URL should be of the form: http://localhost:4502/aem/assetpicker.html/content/dam/we-retail/en/activities?assettype=images

If you require a particular folder to be selected when the asset selector is launched, passed it as a resource suffix.

http://localhost:4502/aem/assetpicker.html?assettype=images&root=/content/dam/we-retail/en/activities
