Using Composite Controls for the implementation of Bootstrap 5 components
You may already be aware that DotVVM 4.0 has introduced a new feature called Composite Controls, which provides a new way to write controls in DotVVM. This approach eliminates the need to declare DotVVM properties in code-only controls, for which you had to use the dotprop code snippet and work with long property declaration blocks. Instead, it only requires declaring a `GetContents` method and placing individual control properties as arguments of the method. By using this approach, the control code appears much more attractive and readable.
