User-friendly Tag Management jQuery Plugin - Selectit.js
Briefly

Key Codes Handling: The plugin listens for specific key presses (Enter, Space, Comma) to trigger the addition of new tags.
Tag Parsing: Parse user input into individual tags.
Tag Addition: Transform each tag into a span element containing the tag text and a hidden input field.
Tag Removal: Tags can be removed by clicking a button, triggering a fade-out animation if enabled.
