In this code: https://smeltejs.com/components/menus the button is not set to block. I set the block property to create a button that spans the width of the page.

<Button dark block on:click={() => open = !open}>{selected}</Button>

When I click the button the menu items do NOT span the width of the menu button. I want the menu items to span the width of the menu button and for the menu items text to be centered like the button.

Using SMELTE I have no idea where or what CSS I need to write to make this happen.
