? Dynamic Dependent Select Option Box using AJAX, JavaScript, and PHP in Hindi

Welcome, on How to Auto Populate Select Dropdown with JavaScript AJAX in PHP in Hindi. Sometimes it requires auto-populate data on the element based on the selection on another element e.g. City names based on a state. You can do this with PHP only but it required you to submit every time on selection. So our goal is to allow the user to select a top-level category from one select box and to automatically populate the sub-category using AJAX. Now, For making it better we can use AJAX with javascript that loads new data and removes the old one on each selection.
