When I create a form in a layout grid, I can not place the radio buttons. That means the buttons always take the full width of the grid.

By design, a radio button is a block element, so it is full width.
But you can use a nested grid to put a radio button on the same row.

In version 14 this was not so, why was this changed now?

It turns out I was wrong. The element is 'inline', but somehow you have managed to turn it into a 'block' element.
If you create a new radio button then it should work correctly.

I will investigate if I can add an option for this.

Thanks for the important feedback. I have now been able to locate the error. I created a new project with the WWB 15 and this page was then imported from a WWB 14 project, but the error occurred. The existing radio buttons had to be deleted and replaced with new ones ....... Now it works.
