Flexdatalist: jQuery autocomplete with support for datalists
Flexdatalist is (another) jQuery autocomplete plugin with support for datalists.
After searching and not finding a standalone, lite (not dependent on jQueryUI), autocomplete that did everything I needed for a project, I created Flexdatalist.
Along with many other cool features, Flexdatalist allows you to style the list of suggested data/values, which is not possible at the moment with browser’s native
Hope it’s useful to you as it is to me. Enjoy ;)

flexselect: Flex-matching Incremental-finding Controls
Flexselect is a jQuery plugin that turns selection boxes into flex-matching incremental-finding controls. Think of it as Quicksilver squished into a selection box.
The difference is a purely aesthetic one — and something that is becoming increasingly popular on more websites. The dropdown selection has a cleaner and more uniform look with this plugin. You can use the mouse to select from the dropdown menu (as you would expect) or click in the Flexselect box and start typing to see options that match those letters appear.
It’s a usability tool that website visitors will love.
To get started, you’ll need to load the default styles, jQuery, the LiquidMetal scoring algorithm and the plugin. Attach the correlating boxes and turn on elements. Then you can enable any custom options that you fancy and start using the plugin. It’s that simple!
With Flexselect installed, you’ll have the exact same functionality made popular by applications like Quicksilver, LaunchBar and Launchy. Nothing makes filling out this type of menu selection as easy as a flexible typing tool.

MagicSuggest: Auto Suggest Combo Box
MagicSuggest is a multiple selection auto suggest combo box for Bootstrap themes. It works similarly to Google search in that when you start typing, it tries to help fill in and suggest options related to your query.
This is a fairly robust tool and can require some setup to make the most of its functionality. You should first decide how you plan to use it. Some examples include a tag box, a filter box, a scrabble box, an email recipients box or for complex templating.
It allows for custom usage based on the needs of your website. You’ll want to do through the pretty extensive documentation to figure out how you can best use it in your design projects.
