This is example demonstrates using MultiSearch to create a message entry form where multiple recipients can be entered. It includes additional logic to show a popover box with data about a previously entered contact. The search performs a lookup against a fictional local address box and accepts only valid email addresses when you want to enter someone not in the address book. There are some extra embellishments for Bootstrap styling to match the widget container to other input controls. Here is a detailed write up on this example and more information about how the Bootstrap focus effect was simulated on the control.
