title: How to add meta tags from widget in Orchard?
body: <p>I'm trying to add some meta tags from widget (/views/parts/ folder) that gets data from database outside of orchard. I need to put them to head section, and frankly I got no idea how to achieve that.</p>
  
  <p>I tried: </p>
  
  <pre><code>using (Script.Head())
  {
   &lt;meta property="description" content="ABC"&gt;
  }
  
  SetMeta("ABC", "description");
  </code></pre>
  
  <p>But none of these work :-(</p>
  
  <hr>
  
  <p>Edit: our document.cshtml code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>@using Orchard.Mvc.Html;
  @using Orchard.UI.Resources;
  @{
      RegisterLink(new LinkEntry { Type = "image/x-icon", Rel = "shortcut icon", Href = Url.Content("~/modules/orchard.themes/Content/orchard.ico") });
  
      string title = Convert.ToString(Model.Title);
      string siteName = Convert.ToString(WorkContext.CurrentSite.SiteName);
  
      string classForPage = "static " + Html.ClassForPage();
  }
  &lt;!DOCTYPE html&gt;
  &lt;!--[if lt IE 7]&gt;
  &lt;html lang="@WorkContext.CurrentCulture" class="@classForPage no-js lt-ie9 lt-ie8 lt-ie7"&gt; &lt;![endif]--&gt;
  &lt;!--[if IE 7]&gt;
  &lt;html lang="@WorkContext.CurrentCulture" class="@classForPage no-js lt-ie9 lt-ie8"&gt; &lt;![endif]--&gt;
  &lt;!--[if IE 8]&gt;
  &lt;html lang="@WorkContext.CurrentCulture" class="@classForPage no-js lt-ie9"&gt; &lt;![endif]--&gt;
  &lt;!--[if gt IE 8]&gt;&lt;!--&gt;
  &lt;html lang="@WorkContext.CurrentCulture" class="@classForPage no-js"&gt; &lt;!--&lt;![endif]--&gt;
  &lt;head&gt;
      &lt;meta charset="utf-8" /&gt;
      &lt;title&gt;@Html.Title(title, siteName)&lt;/title&gt; 
      &lt;meta name="viewport" content="width=device-width"&gt;
  
      @{
          Display(Model.Head);
      }
  
      &lt;meta property="og:title" content="@Layout.Title - @Convert.ToString(WorkContext.CurrentSite.SiteName)"&gt;
      &lt;meta property="og:site_name" content="@Convert.ToString(WorkContext.CurrentSite.SiteName)"&gt;
      &lt;meta property="og:url" content="@Request.Url"&gt;
      &lt;meta property="og:type" content="article"&gt;
  
      &lt;script&gt;(function(d){d.className="dyn"+d.className.substring(6,d.className.length);})(document.documentElement);&lt;/script&gt;
  &lt;/head&gt; 
  &lt;body&gt;
      @Display(Model.Body)
      @Display(Model.Tail)
  &lt;/body&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Does anybody know how to achieve that?</p>
