QueryBuilder is an UI component to create queries and filters.
- It can be used on advanced search engine pages, administration backends, etc.
- It is highly customizable and is pluggable to many jQuery widgets like autocompleters, sliders and datepickers.
- It outputs a structured JSON of rules which can be easily parsed to create SQL/NoSQL/whatever queries.
- And it also comes with a set of great plugins and has a full events system for even more features.
Really neatly programmed solution, with many possible ways to hook into it with your own plugins.
