Autocomplete for each word (or every time space is pressed)

[kgaspard]

This autocomplete script is fantastic, thank you for making it publicly available!

However, for my use case, I need it to display the options every time space is pressed. So let's say, for the sake of simplicity, I have a local suggestion array with "sale price" and "item cost", and I already typed in "how much is my" in the input textbox, is there a way to show those two options when I press space, only "sale price" when I then press 's', then fill in "sale price" at the end of the text (rather than replacing all of it) when I select that option?

Thank you
