ASYNCHRONOUS DROPDOWN LIST DATA LOADING

Example embodiments of a system and method for asynchronous data item loading for a dropdown list of a user interface are described. In an example embodiment, a user input directed to a dropdown list control to cause presentation of at least one of the data items of the dropdown list is received. In response to the user input, a determination is made as to whether the data items are available for presentation. If not, the user input is queued in an event queue, the data items are requested from another computing system via a communication network, and a busy indicator is presented on the user interface in conjunction with the dropdown list control to indicate that the data items are not available for presentation. In response to receiving the data items, the busy indicator is removed, and the user input queued in the event queue is processed.
