A panel to configure JavaScript parameters on a website
<p>I am looking for a library that would create a "settings panel" with configurable amount of sliders, checkboxes, etc and add it to a website. After a slider or checkbox is changed in the panel, a callback function would be executed.</p>

<p>Rationale: I am building a canvas demo and I don't want to spend time on writing my own set of controls for configurable parameters. I want to outsource this job to a small library that does it right.</p>

<p>I saw such thing few months ago but I cannot find it now.</p>
