Typeahead multiple values only triggered on specific character

I am looking for some sort of jQuery typeahead solution which allows a user to select options from a list but only when they enter a certain trigger character and it should also allow multiple values.

For example:

"red","blue","green","orange"

User types re and nothing should happen as it requires [ to trigger

User types [re and then both red and green should be shown as options

Once the user either selects the option from the list or types it and closes with a ] then they should be able to enter more text including another option and another and so on. So if they then type [bl it should show them blue as an option and allow them to choose it etc.

So the end result might look like "re [red] yellow green [blue]" for example - the result is shown simply as text in a textbox so there is no need for any data extraction afterwards
