CKAN Version: >= 2.0
This extension will add pop-up message as tooltip for external URLs. Administrator will be able to add websites to whitelist from UI.
Install the extension as usual, and edit ckan configuration ini file to add or append the plugin:
ckan.plugins = extlink
By default all links except for those from the site’s own domain will be treated as external links, and will have a pop-up message as tooltip when mouse hovered. Site administrators can go to http://yourdomain.site/extlink to add domains to white list, so that those domain links will not be treated as external links. For example:
.mil, data.gov reisys.com reisystems.com
At the same page administrators can also customize the pop-up message.
