How does a Webform able to differentiate among radio buttons, check boxes and Lists I am using webform module to build forms. Initially i created a simple form with few components like text-field, text-area, radios, check boxes , Drop down list and submitted it.

When i checked the database,  I found that the module is storing type "select" for the components radio, check boxes and lists in table name "webform_component". I want to know how can we differentiate them. 

Please check the screenshot, 


While creating the form i choose the following parameters

Gender ----> Radio

Range  ----> List

Hobbies----> Checkbox

But in the table it was shown as "select" for all the fields

Can anyone suggest the way to find out ?
the webform_component table also has an extra column you've cropped out.

It's SQL column help description is:


  Additional information unique to the display or processing of this
  component.


A select can simply be rendered many ways -- I believe the display settings for the "selectable options" used in rendering a radio, list or checkbox are in that column.
