Input Pattern Format

Hi,
I have an input type number.
I want to give it a pattern that only allow input number and - , for example : 1234-2345-3456 .
<input type="number" class="input-with-value" validate pattern="[0-9]*">

Thanks in advance.

It will be [0-9-]*

still not working, the error message still showing up :slightly_frowning_face:
