```
@Retention(RUNTIME)
@Target(TYPE)
public @interface UIHorizontalLayout
```
Marks a group of components horizontally placed next to each other in a HorizontalLayout.
To use this, annotate a class with @UIHorizontalLayout that includes regular UI element annotations like @UITextField on its methods. Call VaadinUiCreator.createComponent(Object, org.linkki.core.binding.BindingContext) with an instance of that class to create the HorizontalLayout and its children.
You can adjust the vertical alignment of the children relative to each other with the alignment() attribute.
