Techniques described herein may provide web pages to customers describing various accounts of the customers. In one implementation, a system receives a request for a web page from a client relating to an account of the client, and generates a document in response to the request. The document includes a reference to a script configured to display a context menu for the account in the web page. The script receives, asynchronously with the display of the context menu in the web page, a menu object representing actions for the context menu that are valid for the account. The system transmits the document and the script to the client.
