Hi, I also need this feature, autocomplete with chip. I'm working on it and it's almost done, I only have one issue:

Is it possible add new tags with javascript? If I add initial tags at the loading of the page

$('.chipfld').material_chip({ data: arr });

It works.

BUT

I need to add them when I click on the options returned by the backend... So I need to trigger a "add new tag" event when I click on something, It's like simulating the "enter key" on the hidden input field created by the jquery chip.

I also tried to make a fresh tab of datas with the new data added

$('.chipfld').material_chip({ data: myNewArr });

but it doesn't work, the tags are not generated...
