I recently filled out a form and when I got to the phone number textBox I noticed some really cool things going on. As I entered my number, general phone symbols were getting added automatically. Example:
I start entering my area code '555'
and my input was changed to 1 (555)
to test what just happened I backspaced on the ) and it quickly added it back in.
So my question is, how do I get this input to happen?
