Hello, Can you share the native docs on this?

Hans Knöchel 2017-05-05

This is no native behavior and therefore we can not support it in the Core. You could just validate the input in your change event, like this:

   myField.addEventListener('change', function(e) {
     const maxLength = 10;
   
     if (e.value.length > maxLength) {
       this.value = this.value.substr(0, maxLength);
     }
   });

Hello Hans, Could you tell me how to access the TextField? I don't see an id attached to the text field. We need an id to attach a change event listener. Thanks,
