          The <code>Dropdown</code> component is used to pass the <code>isOpen</code> & <code>toggle</code> props via context to the following components: <code>DropdownToggle</code>, <code>DropdownMenu</code>. The <code>DropdownToggle</code> uses the <code>Button</code> component internally, meaning it also accepts all the props the <Link to="/components/buttons/">Button component</Link> accepts.

        <h3>Uncontrolled Dropdown</h3>
        <p>
          For the most basic use-case an uncontrolled component can provide the functionality wanted without the need to manage/control the state of the component. <code>UncontrolledDropdown</code> does not require <code>isOpen</code> nor <code>toggle</code> props to work. For the other Dropdown flavors, <code>ButtonDropdown</code>, <code>NavDropdown</code>, uncontrolled components have been made as well; <code>UncontrolledButtonDropdown</code>, <code>UncontrolledNavDropdown</code> respectfully.
