Hide fields on content creation I have added my own content type with many fields to enter, I want to hide some fields when adding a content according to radio button selection.
I explain, in the add content page, i have two radio buttons (inside/outside) and inside is selected by default and some fields are hidden, when user select outside, some fields will be hidden and the fields accorded to outside will be shown to user to fill them.
How to do this ?
You are looking for Conditional Field Module...


  Define dependencies between fields based on their states and values.
  
  Conditional Fields for Drupal 7 is an user interface to the new States
  API, plus the ability to modify fields appearance and behavior on
  certain conditions when viewing content.
