/**
 * Plugin Name: [Forminator] Fix Search Inputs on Selec Fields
 * Plugin URI: https://premium.wpmudev.org
 * Description: When you add a select field on the form and also add an address field with country enabled, the placeholder for all search fields (inside the dropdown options of each one) became the same. And even that you disable the search option in the select field, the search input will be displayed - this plugin fixes these problems.
