Input Formatter Plugin

Could anybody explain step by step how to configuate the plugin used for a telephone number field?
I activated the “Expose the option to add an ID attibute to HTML elements” in settings, and used the ID “Tel”,
but I don’t how to set up the plugin configuration panel. I want to format the Telephone field like this:
(11)1111-1111. The instructions are very poor.
Maybe there is a better plugin to do that?
Thanks a lot!

I don’t know this plugin well, but I think you can try enter this as formatt: 2,4,4

Thanks, but I’ve tried that already.
There’s a lot of fields to fill up, but no documentation how to do it.

Finally Got it! Thanks!!
