DropdownButtonComponent class

A button styled specifically for dropdowns.

By default, this button is rendered with a triangle icon and an underline. The component itself does not have a popup itself but can be used to build dropdowns that are not provided. Use material-dropdown-select for a component that has the same button style, and implements the dropdown itself.
