The thing you are talking about is called google sitelinks, it is not something you can add yourself, it is up to google to add it or not based on your website content quality and SEO. for more information about this topic read these two articles

Just as advice if the website you are talking about is analegg.com ,I recommend you to include your sitemap link on its robots.txt file because when I checked your robots.txt file I found that the sitemap link is missing there and this is a bad practice that many webmasters do not pay attention to.
