Also i want to make radio button fields readonly.

Hi,
this is not possible for now but there is a workaround for select field.

Alternative 1
Follow these step:
1. Set this field to not show on edit profile page
2. Create a field of type "HTML Delimiter" with following configuration:
- set to show only on edit profile page
- set same label of select field
- set in description this:

<select disabled="disabled">

<option>{user alias_of_select_field}</option>

</select>

{user alias_of_select_field} will be replaced by select field value with our content plugin (docs at https://www.easy-profile.com/docs/26-plugin-content.html)

For radio button is more complex, with this way you need many HTML delimiter field for each option (and choose to see one only by the conditions)

Alternative 2
you can make javascript code to add readonly attribute. This alternative is not secure because javascript is client side code and expert users cna change the value of field.

Alternative 3
same as alternative 1 but in description you can show only field value (event input formatting)

{user alias_of_select_field}
