<h2>
Suggestions
</h2>
<p>
Sometimes it's useful to <strong>mention</strong> someone. That's a feature we're very used to. Under the hood this technique can also be used for other features likes <strong>hashtags</strong> and <strong>commands</strong> lets call it <em>suggestions</em>.
</p>
<p>
This is an example how to mention some users like <span data-mention-id="1">Philipp Kühn</span> or <span data-mention-id="2">Hans Pagel</span>. Try to type <code>@</code> and a popup (rendered with tippy.js) will appear. You can navigate with arrow keys through a list of suggestions.
