Auto-resize height of headers and footers

[marcheimendinger]

Is your feature request related to a problem? Please describe. It's annoying to always have to manually set the viewHeight of a header or footer view as we don't already want a static value, depending of the content and screen size.

Describe the solution you'd like A simple boolean value to enable autoresizing height of headers and footers, based on the content (for example the whole text of the label becomes visible without setting a static height value).
