Question

Is VForm suppose to have a valid value of true if a required field is programmatically set to null or undefined?

If this is intended behavior, how do you clear a field without making the label float?

Like this:

Instead of:

I understand that an empty string is considered a valid value (as discussed here), but this raises the question: how can you clear a field and trigger validation without causing the label to float? Should null or undefined trigger form validation?

How to Reproduce

1. Go to example
2. Click on Set to null or Set to undefined
3. See that valid stays true
4. Click on Set to empty string
5. See that valid is false but the label floats

Example

In this example a VSelect component is used, but it can also be reproduced with a VTextField component.
