Two dropdown menus are present, where the second dropdown menu is dependent on the selection made in the first dropdown. However, after refreshing the page following an ajax update, the second dropdown does not retain the previously selected choice. How can this be achieved using Javascript?
There are several options available for handling this situation. One approach could be to utilize the localStorage API for saving the selection from the initial dropdown menu. When the page loads, check if there is a saved value and use it to pre-populate the first dropdown while triggering its change event to update the second dropdown accordingly.
For more details on how to use localStorage, refer to this link: https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#localStorage
