Custom Style on React-Bootstrap's Dropdown Menu component

Question

I am trying to apply a custom css style to a react bootstrap component, but cannot figure how to access elements that are not explicit in the component's JSX. For example:

<ButtonGroup>
      <DropdownButton className="ddown" id="ddown" title="Dropdown">
      <MenuItem className="itemxx" href="#books">Books</MenuItem>
      <MenuItem className="itemxx" href="#podcasts">Podcasts</MenuItem>
      <MenuItem className="itemxx" href="#">Tech I Like</MenuItem>
      <MenuItem className="itemxx" href="#">About me</MenuItem>
      <MenuItem className="itemxx" href="#addBlog">Add a Blog</MenuItem>
      </DropdownButton>
    </ButtonGroup>

has no outlet for the Dropdown box, which I am looking to give a specific width and eliminate its rounded corners. Is there a way that I can access it in my css?

EDIT:

Here is the element I want to edit, which by the way if I try to access through .dropdown-menu, 1) I change all dropdowns, and 2) I cant change most of its values.

Answer 1

Add a custom className to <MenuItem></MenuItem> and edit it by appending a a at the end of className in your .css file while customising.

In your .js file:

<MenuItem className="dropdown-link"> DaItem </MenuItem>

In your .css file: (Note the a in the selector)

.dropdown-link a {background: red; color: yellow;}

P.S: You may need to add !important in .css
