Removing the border from a themeable Menu

[Aris]

Hi!

I do not know if it's a simple problem, but I find it difficult:

I put a Themeable Menu --with a blue background-- inside a layout grid of the same color.
It is impossible to me removing the white outline of the Themeable Menu.

What am I doing wrong?

Thank you.

You can use same border color as the background or set the alpha value to zero.

Thank you, Pablo.
