Click the image below to view a set of screenshots showing the prototype whitelist maintenance which features (make sure to read the full article for open issues!):

• DataTables display (sorry, nothing fancy a la export, changing columns, etc., for this simple function)
• Inline editing and validation with drop down selection of whitelist type courtesy of jQuery Editable, DataTables, and the DataTable Editable plugin
• Modal popup to add a whitelist entry
• Select rows to remove (delete)

B C D E F G H

A few caveats / issues to resolve:

• None of the back end code to store the changes, insert additional whitelist entries, or delete existing whitelist entries exists yet (that's the next step)
• Adding records requires non-compliant HTML (an extra attribute)
