jQuery UI & Autocomplete: Multiple entries with values

This entry is part 6 of 7 in the series jQuery UI Autocomplete

jQuery UI Autocomplete – Multiple values

Usage: Type something, eg. “j” to see suggestions for tagging with programming languages. Select a value, then continue typing to add more.

This is an example showing how to use the source-option along with some events to enable autocompleting multiple values into a single field.
