Bootstrap is a clean, flexible and popular front-end framework and collection of interactive components built on HTML, CSS and JavaScript. Open-sourced by Twitter — the microblogging pioneer — in August 2011 as a complete front-end solution, it ships with very thorough and detailed documentation; with it, web developers can easily put together clean-styled interfaces and achieve great interaction effects. Twitter Bootstrap’s slogan is that it fits any scenario and fits everyone, and more and more developers are actively adopting Bootstrap today. Just a few weeks ago Bootstrap released its latest version with many improved and new features. Bootstrap is by far the most comprehensive front-end framework and is genuinely suited to rapid prototyping and back-end/CMS development tools. This article collects 13 excellent Twitter Bootstrap JavaScript extension plugins — with Bootstrap, developers can save a great deal of time fixing cross-browser layout problems and build web interfaces of every kind.
1. Fuel UX 
Fuel UX is a lightweight plugin for Twitter Bootstrap. Its components include a number of practical plugins such as ComboBox, Datagrid, Pillbox, Search and Spinner.
2. BootMetro 
BootMetro can turn Bootstrap into a Microsoft Metro UI. In addition, the JavaScript plugins that come with BootMetro support Metro behaviour very well.
3. WYSIHTML5 
WYSIWYG HTML5 is a very attractive web editor, with fairly comprehensive configuration and events that can meet your needs.
4. jqBootstrap Validation 
I really like Bootstrap’s default style. If you want a theme that stands out from the crowd, this plugin can help you.
5. ColorPicker 
This plugin lets you add color fields and supports a variety of color styles.
6. DatePicker 
Datepicker lets you attach it to text or any element, and it is often used as a component supporting multiple date formats.
7. TimePicker 
If you have a date picker, you will certainly want to edit the date yourself. This plugin makes it easy to enter text using just the mouse or the arrow keys.
8. DateRange Picker 
If you have ever used Google Analytics, this JavaScript plugin will feel very familiar. DateRange is extremely useful for generating reports or collecting appointment dates.
9. Bootbox JS 
Create programmatic dialogs using Twitter Bootstrap’s existing patterns. Bootbox is a very flexible and powerful JavaScript dialog library.
10. jQuery UI Bootstrap 
This one has a theme similar to Twitter Bootstrap, and most importantly, if you want to integrate Bootstrap with jQuery UI, this theme will make them look far more consistent.
11. jQuery File Upload 
HTML5 Ajax-based file upload. The basic implementation is quite good, and there are plenty of examples to demonstrate here.
12. DataTables 
DataGrid is similar to Fuel UX, supporting sorting, paging, search and other features.
13. Bootsnipp 
Bootsnipp is unlike any JavaScript plugin — you copy and paste layout code snippets. It gathers commonly used UI pieces, including login screens, window modes, tables, navigation bars and much more; you can grab the code and use it immediately.
