React-Bootstrap的下拉菜单组件上的自定义样式 [英] Custom Style on React-Bootstrap's Dropdown Menu component

问题描述

我尝试将自定义css样式应用于react bootstrap组件，但无法弄清楚如何访问该组件的JSX中未显式的元素.例如:

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>

没有下拉框的出口，我希望提供特定的宽度并消除其圆角.有没有办法可以在CSS中访问它?

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?

这是我要编辑的元素，顺便说一下，如果我尝试通过.dropdown-menu进行访问，则1)我更改了所有下拉菜单，并且2)我不能更改其大部分值.

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.

推荐答案

自定义时，将自定义className添加到<MenuItem></MenuItem>并通过在.css文件中className末尾附加a进行编辑.

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.

在您的.js文件中:

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

在.css文件中:(请注意选择器中的a)

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

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

P.S:您可能需要在.css

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