我在Navbar中嵌套了以下代码:
<Navbar inverse collapseOnSelect fixedTop fluid>
<Navbar.Collapse>
<Nav onSelect={this.props.onSelect} pullRight>
<NavItem eventKey={'navItem1'}>NavItem 1</NavItem>
<NavItem eventKey={'navItem2'}>NavItem 2</NavItem>
<NavDropdown eventKey={'dropdown1'} title="Dropdown1" id="basic-nav-dropdown">
<MenuItem eventKey={'placeholder1'}>Placeholder</MenuItem>
<MenuItem divider />
<MenuItem eventKey={'placeholder2'}>Placeholder</MenuItem>
</NavDropdown>
<NavDropdown eventKey={'dropdown2'} title="Dropdown2" id="basic-nav-dropdown-2">
<MenuItem eventKey={'placeholder3'}>Placeholder</MenuItem>
<MenuItem divider />
<MenuItem eventKey={'placeholder4'}>Placeholder</MenuItem>
</NavDropdown>
<NavDropdown eventKey={'dropdown3'} title="DropDown3" id="basic-nav-dropdown-3">
<MenuItem eventKey={'placeholder5'}>Placeholder</MenuItem>
<MenuItem divider />
<MenuItem eventKey={'placeholder6'}>Placeholder</MenuItem>
</NavDropdown>
</Nav>
</Navbar.Collapse>
</Navbar>
我面临的问题是只有Dropdown1会显示下拉列表。在使用我的ChromeTools查看问题时,似乎其他两个下拉菜单没有打开&#34;打开&#34;课程加入了他们。
有什么建议吗?

您的NavDropdown组件本身没有事件键,它们只有标题和ID值。它应该是这样的:
<NavItem eventKey={1}>NavItem 1</NavItem>
<NavItem eventKey={2}>NavItem 2</NavItem>
<NavDropdown eventKey={3} title="Dropdown1" id="basic-nav-dropdown">
<MenuItem eventKey={3.1}>Placeholder</MenuItem>
<MenuItem divider />
<MenuItem eventKey={3.2}>Placeholder</MenuItem>
</NavDropdown>
<NavDropdown eventKey={4} title="Dropdown2" id="basic-nav-dropdown-2">
<MenuItem eventKey={4.1}>Placeholder</MenuItem>
<MenuItem divider />
<MenuItem eventKey={4.2}>Placeholder</MenuItem>
</NavDropdown>
