+Label modifier for select and boolean fields
+---------------------------------------------
+
+For select and boolean field types, you can display the human-readable label instead of the stored value by using the ``|label`` modifier:
+
+.. code-block:: php
+
+    {contactfield=select_alias|label}
+    {contactfield=bool_alias|label}
+
+This is useful when your select fields store technical values but you want to display user-friendly labels in your Emails. For example:
+
+- A country select field storing ``us`` can display ``United States``
+- A boolean field storing ``1`` can display ``Yes``
+
+The modifier also works with company fields:
+
+.. code-block:: php
+
+    {contactfield=company_select_alias|label}
+    {contactfield=company_bool_alias|label}

+Label modifier for select and boolean fields
+=============================================
+
+For select and boolean type fields, you can use the ``|label`` modifier to display the human-readable label instead of the stored value. This is particularly useful when your select fields store values like codes or IDs but you want to display friendly labels to your Contacts.
+
+**Syntax:**
+
+.. code-block:: text
+
+    {contactfield=field_alias|label}
+
+**Examples:**
+
+For a select field with alias ``country_select`` that has options like ``us`` (United States), ``uk`` (United Kingdom):
+
+- ``{contactfield=country_select}`` - displays the value: ``us``
+- ``{contactfield=country_select|label}`` - displays the label: ``United States``
+
+For a boolean field with alias ``is_subscriber``:
+
+- ``{contactfield=is_subscriber}`` - displays the value: ``1`` or ``0``
+- ``{contactfield=is_subscriber|label}`` - displays the label: ``Yes`` or ``No``
+
+This modifier works for both Contact fields and Company fields:
+
+- ``{contactfield=company_type|label}`` - displays the label of a company select field
+- ``{contactfield=company_active|label}`` - displays the label of a company boolean field
+
+.. note::
+    The ``|label`` modifier only works with select and boolean field types. For other field types, it will display the regular value.
