1. As mentioned before, if you go to the main page of the demos, scroll down to “Sample Applications”, you have a “Form” application listed. But that leads to the DropDownList demo page, where all the forms are just mock-up forms. That’s misleading.
2. It seems that setting “display:block” on all the widgets in the form is mandatory, otherwise you end up with strange, uneven spacing like in my pictures. Thank you for pointing out. Maybe you could add a document describing how to create a proper form.
3. I see. I guess I was mislead by the fact that the TextBox overview page shows the label in one of the animated gifs (see below) and the API page has both label and hint properties listed, without being mentioned that those are experimental features only.
