Hello! Great library - really enjoying it!

For our device setup / registration we need the user to enter their email, as shown below. We would like this field to be required, so the user can't press save without entering a value for this space, preferably with some sort of email syntax validation checking (if that's a built in HTML feature).

I was able to configure other aspects of the captive portal page, but couldn't find an easy way to make a parameter entry required by the user (as a HTML change). Is there an easy way to do this through the current API?

Thank you so much!

Nvm, figured it out from other issues (sorry missed this before due to slightly different terms for the same thing).
Issue: https://github.com/tzapu/WiFiManager/issues/736

FYI this was my ultimate solution's syntax:

WiFiManagerParameter("email", "User Email Address", "", 50,"type=\"email\" required");

Changing the type to "email" for minor syntax-checking (ain't perfect, but still something), and the required field so the user can't hit "save" without populating this field.

Thank you!
