I'm using the "select2" type of field for several fields in my form.
Everything works as expected, but once a value is selected and saved i cannot "empty" or reset the value anymore.
I get an "Add" and a "Edit" buttons beside the dropdown, but I need a "reset" button too.
Those fields are not required.
How can i do this?
I don't want to add a "no value" record to the table.
I used the "first_option" parameter, as suggested by admin, but i had to implement the "on_before_save" function to replace the "0" value to NULL. Otherwise, the "0" is saved.
$fields['lugar_nacimiento_provincia_id']['first_option'] = array(0=>' ');
Is there a better way to do that in order to avoid the on_before_save changes?
$fields['lugar_nacimiento_provincia_id']['first_option'] = 'Select one...';
And no default value for that field in the db.
It's OK, it's not a big problem keeping the on_before_save hooks I implemented.
Thanks for your help!
