I posted this on the farcry-dev mailing list but thought I would post it here as well to help future googlers in need.

I have created a slider formtool for a client and thought it could be useful to others in the community. You can find the source for it here: https://gist.github.com/1230366

To use, simply download the CFC, and place it in your project’s /farcry/projects/projectname/packages/formtools directory. Once there, you specify the metadata in your custom types as you would use any other formtool.

The formtool is an extension of the numeric formtool found in core, so you can use any of the features found from that formtool in the slider (ftPrefix, ftSuffix, etc).

The slider formtool adds 4 new metadata options. ftMin, ftMax, ftStep, and ftOrientation. Min and Max are the lowest and highest values allowed for the field. ftStep is the increment factor the slider will use. If you specify one, each slide of the slider will move the value by 1, if you specify 0.5, it will increment it by 0.5 (1, 1.5, 2, etc). ftOrientation can be either “horizontal” or “vertical” and it will orient the slider either horizontally or vertically.

Your users can either type a value into the text box or use the slider to select a value.

This uses the jQuery UI Slider widget so you can use it with FarCry 6+ since core ships with jQuery UI built in.

If you find it useful, missing a feature, broken, etc please let me know. Consider it released under a “do whatever you want with it” license.
