title: How can I open a modal from a navbar with react-bootstrap?
body: <p>Currently, I have a <code>nav</code></p>
  
  <pre><code>  &lt;Nav pullRight className="navright"&gt;
      &lt;NavItem href="#" className={this.state.signedIn ? '' : 'hidden'}&gt;{this.state.name}&lt;/NavItem&gt;
      &lt;NavItem eventKey={2} href="#" className={this.state.signedIn ? 'hidden' : ''}&gt;Login&lt;/NavItem&gt;
      &lt;NavItem eventKey={1} href="#" className={this.state.signedIn ? 'hidden' : ''}&gt;Sign Up&lt;/NavItem&gt;
    &lt;/Nav&gt;
  </code></pre>
  
  <p>I don't know what <code>eventKey</code> is or if it's needed. But I want to open up my modal (called <code>AuthModal</code>) when either of those are clicked. I want to open <code>AuthModal</code> passing an attribute of either <code>'login'</code> or <code>'signup'</code></p>
  
  <p>How can this be done? I'm using <code>redux</code> if that matters.</p>
