How to add radio button in drupal profile page
By using the Profile Checkboxes module, you can be able to add radio buttons in the Drupal profile page.


Download the Profile Checkboxes module, and install it.
If you need to create a radio buttons field, click "List selection" in "Add new field."
In that page, you will find the "Selection options" option with a text area field. Enter the radio button details here. For example, if you are adding the gender, enter "Male" and in next line enter "Female."
Now, at the bottom of the page you will find the "Profile checkboxes" tab.
There you select the "Radio buttons (single choice)" and save.
