<md-select-option>
Select menus display a list of choices on temporary surfaces and display the currently selected menu item above the menu.
The select component allows users to choose a value from a fixed list of
available options. Composed of an interactive anchor button and a menu, it is
analogous to the native HTML <select> element. This is the option that
can be placed inside of an md-select.
This component is a subclass of md-menu-item and can accept the same slots,
properties, and events as md-menu-item.
