How to hide "User Information" options from "My Account" in Liferay 6.1?

I am trying to hide some options in "User Information" from My Account by using hook. I just want to hide it using CSS (style="display:none"). User Information is present in the right side of My Account Page. I want to know, in which page I should make changes? While creating hook which page I should select for hiding those links like "Organizations, Sites, etc." Please help...

Solution

It is not possible to remove those options using CSS. We can do the following simple java code for removing those tabs... The page which we need to edit is "/portal-trunk/portal-web/docroot/html/portlet/users_admin/edit_user.jsp".

List<String> identificationList = new ArrayList<String>();

for(String identificationItem : identificationSections){
    identificationList.add(identificationItem);
     System.out.println(identificationItem);
}
identificationList.remove("websites");
identificationList.remove("instant-messenger");
identificationList.remove("social-network");
identificationList.remove("sms");
identificationList.remove("open-id");

identificationSections = new String[identificationList.size()];
for(int i = 0; i < identificationList.size(); i++){
    identificationSections[i] =identificationList.get(i);
}

Its easy to hide those links by using the simple java code written above.
