Link custom field

You use the Link custom field to set links in your site to make it easy for your audience to redirect to related content. It displays a link selector that allows you to insert links to existing pages or content items from Sitefinity CMS, enter an external link (URL) or email address, which you want to link the current item to. 
The Link custom field is available for both static and dynamic content types and can be single-select or multi-selecttype.
