1. eap It contains the reusable qml for different types of authentication method like fast, leap etc for enterprise networks
2. enterprise containts the complete qml for enterprise network type
3. WifiSecurityForm wraps all those qml in form of a combo box
4. PasswordField A reusable password form field that can be used both as an applet and inline field. (refactor of applet/PasswordField.qml)

The main design component is using Kirigami.FormLayout which helps to resize the necessary qml automatically on plasma-mobile
