SP2013. Adding breadcrumbs
For some reason breadcrumbs are disabled in the default SharePoint master pages. Luckily it is very easy to add them.
Simply add this snippet to your master page or page layout
<!--MS:<asp:sitemappath runat="server" sitemapproviders="SPSiteMapProvider,SPXmlContentMapProvider" rendercurrentnodeaslink="false" hideinteriorrootnodes="true">--> <!--ME:</asp:sitemappath>-->
Navigate up (breadcrumb fly-out)
If you are used to SP2010 or SP2007 you might also know the navigate up icon. When you click it, a flyout appears with the breadcrumb
To add this one to your SP2013: edit the master page (or actually the html). Look for a div with the css class ‘ms-breadcrumb-top‘. In this div you find a SharePoint control called PopoutMenu.
For some reason this ‘PopoutMenu’ control has the attribute ‘visible’ set to ‘false’. Remove the complete attribute or replace the visible=”false” by Visible=”true”
The result will be an icon that when clicked results in a breadcrumb popout.
