External: This is the default behavior for Attachment/Free Attachment links. When a link to a file is clicked, the file will open in the applicable application (image viewing software for .png’s, jpg’s, for example). When a link to a URL is clicked, the URL will load into the same web browsing window. Lightbox: Links to files or URLs with this attribute are assumed to be links to image files or URLs. When the link is clicked, a Lightbox link will create a popup window and expose the image, which will sit on top of the current window (Figure 68). Figure 68 Enter Value: After you select “Enter Value” from the drop-down list, the word “custom” will appear in the Link Rel field. Technical staff can then enter custom values for the Link Rel attribute. See Tech Tip below. Tech Tip: For technical information about customizing the Attachment/Free Attachment Link Rel, see the “Link Roles: Rel Attributes” section of the Tizra Developer documentation here: https://github.com/Tizra/Tizra-Customer- Tracker/wiki/Reader-2.0 Note: The Attachment/Free Attachment Link Rel settings only control how links that are made visible in the Downloads section of the online content reader will behave. To control how links within a PDF behave, see the following Tizra Developer documentation: https://github.com/Tizra/Tizra-Customer- Tracker/wiki/Customized-Links-In-PDFs TT
