Where is the 'Please fill in this field' popup coming from

[zdam]

Hi,

I have added required attributes to some of my fields in a form, now when I attempt to submit, I get a little popup with a exclamation mark that says 'Please fill in this field'

Where is this coming from, how can I control it? 

I have tried using the css classes ng-invalid, ng-valid, ng-pristine, ng-dirty, but this has not affected this little popup.

Thanks, Adam.

It's an HTML5 feature with browser-specific implementations, see

Add novalidate to your form tag : <form name="myForm" novalidate>
