Survey forms, as the name of the component reminds, are not part of the component. These forms are supposed to be created at Google Drive and then copied to the component. The best thing is that user responses will be stored at Google Drive Spreadsheet so they can be easily processed.
Individual steps can be submitted either by submitting the form of by countdown.
Menu item can point to any step or to list of all steps.
Gform is easy to install, well documented and easy to use. The support is really good, and the developer is very helpful to upgrade the extension to your needs (pe validation of required questions). And this all for free!
The only con is that you have to switch to "no editor" in your user profile every time you want to edit a form. But once you get used to that, it works perfectly.
The extension is very simple to use, you can create a survey using google drive documents and add the code in your web site, It will automatically save the result
of the survey in your google drive file.
So you can use this file to create graphics or share it.
I am also using this extension to create simple mask that brings data and save it
in a google drive file.
This extension is Non-Commercial, is well developed and I have reveived an excelent help by the developer, how can I say ? Thanks!
I suggest to try and use this simple extension to every one.
