title: How to fix 'button' interactive role must be focusable
body: <p>I have list of dropdown options which user can select.</p>
  
  <p>optinos in dropdown are made with tag: &lt; a href>:</p>
  
  <pre><code>&lt;a onClick={() =&gt; handleSelect(filter)} role="button"&gt;
     {filter.name}
  &lt;/a&gt;
  </code></pre>
  
  <p>Problem is cus I must add <code>tabIndex="0" or -1</code>, to fix error from Eslint. </p>
  
  <p>But When I add <code>tabIndex=0</code>, my button does not work anymore. </p>
  
  <p>Is there are any other way to fix this error?</p>
  
  <p>This is how looks dropdown component:</p>
  
  <pre><code>&lt;ul name="filters" className="dropdown"&gt;
      {filterOptions.map((filter) =&gt; (
        &lt;li
          key={filter.id}
          defaultChecked={filter.name}
          name={filter.name}
          className={`option option-${filter.selected ? 'selected' : 'unselected'}`}
        &gt;
          &lt;span className={`option-${filter.selected ? 'checked-box' : 'unchecked-box'} `} /&gt;
  
          &lt;a onClick={() =&gt; handleSelect(filter)} role="button"&gt;
            {filter.name}
          &lt;/a&gt;
        &lt;/li&gt;
      ))}
    &lt;/ul&gt;
  </code></pre>
