Thanks @Anu6is

Is it possible to add also HeaderStyle parameter?

Is it possible to add also HeaderStyle parameter?

You can create a css class with the style you want applied and add that to the HeaderClass. I believe Mud is moving away from adding numerous Style properties to the components and preferring the use of Class.

I will, thanks!

@w3ori note the original PR description notes adding TitleClass and TitleStyle however the Style was removed 289c43b after being reviewed.
