Define a custom placeholder and the search input placeholder in the Select field, instead of the native “Select” text.
|Placeholder||Appears within the input|
|Search Input Placeholder||Appears within the search input|
Allow users to type and select a custom value within the search function of the Select field.
The Stylised UI setting (Select2 library) has been enhanced to fit the WordPress Admin UI. The field style has been harmonized and looks like any other Select input.
