Hello and thks for your nice work !
I would like to know if it’s possible to replace the autocomplete “To” field in the new message box by a simple select ?
Is there any action, filter, option or a simple method to do that whithout braking the source code ?
This plugin is developer friendly. There are many ways to do this without changing code plugin code.
If you have php knowledge please have a look at front-end-pm-pro/includes/class-fep-form.php. You can use fep_form_fields filter hook to change type or fep_form_field_output_message_to action hook to change output.
Let me know if you need any more assistance.
