It's a simple jQuery plugin that enables an input to filter an <ul> list.
It shows/hides items that match/don't match the query on the input. Check the demo.
Just set the data-searchable-target attribute or use the option search_target when you make an input searchable to set the target (an <ul> tag)
As far as it is useful for you, you're free to do with it whatever you want. Christian Córdoba.
