What it does
This class handles boolean (Yes/No) customer attribute form elements in Magento 2.
It extends the Select form element to provide specific text representations for boolean values, converting '0' to 'No' and '1' to 'Yes' for display purposes.
Developers use this when working with customer attributes that require true/false or yes/no selections in forms.
