Forms

Forms allows the creation of shareable forms, with multiple question types and privacy settings.

Note: This app is tested with Apache2 webserver, MySQL database, and apt-get package manager. To use alternatives, replace the relevant commands with those of your technology. This document assumes that a working NextCloud development environment has been installed. See https://docs.nextcloud.com/server/stable/developer_manual/general/devenv.html for help with this.
