marcdecroux on "[Plugin: Contact Form 7] Clear a field before enter text"

Hello !

I setup a form with the label inside the fields :
[text* name 50/ watermark="name"]

This works great. But some user doesn't erase the texte before typing their name! Is it a way to automatically erase the field as soon as the click on it or goes on this field with the tab button? In javascript it's easy : onFocus="this.value=""". But to to do the same with Contact7?

Thanks a lot for your help!

Best regards!
