Our field:

<label> Apartment/Town Home Needing Maintenance *
[post_select* apartment posts-number:-1 publish include_blank search_box post-type:property value-field-meta-key:wpcf-property-contact-email value-field:meta orderby:title order:ASC “%title%”] </label>

Question:

If I want to show the title instead of the wpcf-property-contact-email value in the Mail template, how to I modify [apartment] in the Mail template?

Thanks
