 The SelectMenu component renders by default a [Select](/forms/select) component and is based on the `ui.select` preset. You can use most of the Select props to configure the display if you don't want to override the default slot such as [color](/forms/select#style), [variant](/forms/select#style), [size](/forms/select#size), [placeholder](/forms/select#placeholder), [icon](/forms/select#icon), [disabled](/forms/select#disabled), etc.
