1. Can you please show me the code where the forms are created on that Sample app? In the source code at the bottom of the page I can’t locate any smart-text-box or similar.
2. I know how to change the style. I just don’t understand why, by default, similar widgets (which usually are side by side in forms) have different styling.
3. Actually labels are listed among the features in the TextBox overview page. In any case, even if I don’t use labels and hints, the layout has some issues, as you can see in the next picture. I can’t figure out where that extra space after (or before?) some inputs comes from.

Any help to create that simple form is much appreciated.
