This is the code which causing the error,

<pre><code>&lt;NavLink href="#x"&gt;&lt;Link id="RouterNavLink" style={None} to="/contact"&gt;anywords&lt;/Link&gt;&lt;/NavLink&gt;
</code></pre>

Which is converted to,

<pre><code>&lt;a&gt;&lt;a&gt;&lt;/a&gt;&lt;/a&gt;
</code></pre>

So you are getting error,

<pre><code>Warning: validateDOMNesting(…): &lt;a&gt; cannot appear as a descendant of &lt;a&gt;
</code></pre>

To solve this just use one of the follow,

<pre><code>&lt;NavLink id="RouterNavLink" style={None} to="/contact"&gt;anywords&lt;/NavLink&gt;
</code></pre>

OR,

<pre><code>&lt;Link id="RouterNavLink" style={None} to="/contact"&gt;anywords&lt;/Link&gt;
</code></pre>

entityMap|blocks|key|7fbcj|text|添加|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5mviu|将属性(以前称为componentClass)添加到原始NavLink以保持样式不变，同时使警告保持静音。|9aoqu|https://react-bootstrap.netlify.com/components/navs/#nav-link-props|bsfp5|或者|2oiu9|查看屏幕截图|6fgh6|原件：|59jag|新增：^0|0|0|0|0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|O|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|P|9|@]|A|@]|B|$]]|$2|E|4|F|6|7|8|Q|9|@]|A|@]|B|$]]|$2|G|4|H|6|7|8|R|9|@]|A|@]|B|$]]|$2|I|4|J|6|7|8|S|9|@]|A|@]|B|$]]|$2|K|4|L|6|7|8|T|9|@]|A|@]|B|$]]|$2|M|4|N|6|7|8|U|9|@]|A|@]|B|$]]]]

Add the <code>as</code> prop (formerly <code>componentClass</code>) to your original <code>NavLink</code> to keep the styling while also silencing the warning.

entityMap|blocks|key|36ont|text|我想提出一个替代方案，它不仅能解决你的问题，而且能给你想要的结果。无论如何，其他人也像我一样偶然发现了这篇文章。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|360nd|使用react路由器dom提供的Link+jsx元素，但添加|2cfne|为它干杯。这将为您提供react+strap正在使用的NavLink+jsx的样式。^0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|G|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|H|9|@]|A|@]|B|$]]|$2|E|4|F|6|7|8|I|9|@]|A|@]|B|$]]]]

I would like to suggest an alternate solution which not only solve your problem but give you desired result. In any case someone else stumbled on this post like I did.
Use Link jsx element offered by react router dom but add <code>classname=&quot;nav-link&quot;</code> to it. This will give you styling of the NavLink jsx which react strap is using.

I'm trying to use react-router with reactstrap in a create-reat-app .In the
routing page i needed to use state for the reactstrap so i converted the router from a variable to a class.I get this warning : 
Warning: validateDOMNesting(...): 
<code>&lt;a&gt; cannot appear as a descendant of &lt;a&gt;.</code>
i don't know what to do ?, i needed to style the router navigation using reactstrap so i did what you see below .

This didn't work for so many reasons :

<pre><code>&lt;NavLink componentClass={Link} href="/contact" to="/contact" active={location.pathname === '/contact'}&gt;anywords&lt;/NavLink&gt;
</code></pre>

<pre><code>&lt;Navbar dark id="RouterNavbar" expand="md"&gt;
 &lt;NavbarBrand id="NavBrand"href="#x"&gt;&lt;ul&gt;(a bunch of li not relevant)&lt;/ul&gt;&lt;/NavbarBrand&gt;
&lt;NavbarToggler id="NavBarToggler" onClick={this.toggle1.bind(this)} /&gt;
 &lt;Collapse isOpen={this.state.isOpen1} navbar&gt;
 &lt;Nav className="ml-auto" navbar&gt;
 &lt;NavItem&gt;
 &lt;NavLink href="#x"&gt;&lt;Link id="RouterNavLink" style={None} to="/contact"&gt;anywords&lt;/Link&gt;&lt;/NavLink&gt;
 &lt;/NavItem&gt;
(then just more of the above)
</code></pre>

other than a couple of li coming close to each other at random times and me having to refresh the page sometimes instead of the normal behaviour (auto refresh ) and the warning message i get in the console ,nothin bad happens but when i read about this issue i found out that i shouldn't do it.

Warning: validateDOMNesting(...): <a> cannot appear as a descendant of <a>
