*a.k.a “The Grand Input Bazaar”*

\n\n

\n\nA collection of assorted fancy inputs, odds and ends — with which to produce values to feed your burgeoning sketches. All inputs support optional **titles** and **descriptions**; where it makes sense, inputs also support a **submit** option, which allows you to prevent the value from updating until the input has been finalized.\n\nWares we have on offer: \\`slider\\`, \\`button\\`, \\`color\\`, \\`date\\`, \\`file\\`, \\`text\\`, \\`textarea\\`, \\`radio\\`, \\`checkbox\\`, \\`number\\`.\n\n*Although hopefully we’ll have a better way to send patches soon — for now, please email me any improvements you’d like me to incorporate here.*`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":128,"value":"md`---\n## Sliders\n\n\\`import
