Module documentation for 1.7.6

yesod-form

Form handling for Yesod, in the same style as formlets. See the forms chapter of the Yesod book.

This package provides a set of basic form inputs such as text, number, time, checkbox, select, textarea, and etc. via Yesod.Form.Fields module. Also, there is Yesod.Form.Nic module providing richtext field using Nic editor. However, this module is grandfathered now and Nic editor is not actively maintained since June 2012. You can find additional richtext editor fields in yesod-form-richtext package (currently in provides support of Summernote editor only).
