Adding a icon to React Bootstrap Dropdown

Question

I'm trying to add an icon to my react dropdown button as shown in the following button.

I couldn't find a way to implement this with the react bootstrap package i'm using.

https://react-bootstrap.github.io/

I tried using the normal bootstrap 4 to to this. But found out that it needs jquery to open the dropdown menu. How can i add a icon to my react bootstrap drop down?

My code

   <DropdownButton id="example-month-input-2" title={this.state.weekselectedType}>
         <Dropdown.Item onClick={() => this.changeWeekValue('a')}>A</Dropdown.Item>
         <Dropdown.Item onClick={() => this.changeWeekValue('b')}>B</Dropdown.Item>
         <Dropdown.Item onClick={() => this.changeWeekValue('c')}>C</Dropdown.Item>
   </DropdownButton>

I managed to remove the default dropdown icon using the following css

.dropdown-toggle::after {
    display:none !important;
}

React Bootstrap allows you to customise Dropdown by passing in custom subcomponents. To customise the toggle button, you can use:

// The forwardRef is important!!
// Dropdown needs access to the DOM node in order to position the Menu
const CustomToggle = React.forwardRef(({ children, onClick }, ref) => (
  <a
    href=""
    ref={ref}
    onClick={e => {
      e.preventDefault();
      onClick(e);
    }}
  >
    {/* Render custom icon here */}
    &#x25bc;
    {children}
  </a>
));

render(
  <Dropdown>
    <Dropdown.Toggle as={CustomToggle} id="dropdown-custom-components">
      Custom toggle
    </Dropdown.Toggle>

    <Dropdown.Menu>
      <Dropdown.Item eventKey="1">Red</Dropdown.Item>
      <Dropdown.Item eventKey="2">Blue</Dropdown.Item>
      <Dropdown.Item eventKey="3" active>
        Orange
      </Dropdown.Item>
      <Dropdown.Item eventKey="1">Red-Orange</Dropdown.Item>
    </Dropdown.Menu>
  </Dropdown>,
);

here's with the Icon

<DropdownButton id="example-month-input-2" title= 
{this.state.weekselectedType}>
     <Dropdown.Item onClick={() => this.changeWeekValue('a')}><i 
 class="fa fa-chevron-down"></i></Dropdown.Item>
     <Dropdown.Item onClick={() => 
this.changeWeekValue('b')}>B</Dropdown.Item>
     <Dropdown.Item onClick={() => 
this.changeWeekValue('c')}>C</Dropdown.Item>
</DropdownButton>
