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.
