Changing the html page tag. how to add an option?

Question

PHP

Greetings!

There is an html: select element with different options.

Please tell me how to make it possible to add new options to this select through a text field by pressing a button so as not to climb into the code every time.
That is, I entered a new value for the drop-down menu in the text field, clicked the button, and this new value will be entered into the html code of the page and saved.

Thank you!

You need PHP MySQL AJAX
In order to save - it would be more correct to store the selector fields in the database, when you click on the button, you send an Ajax request with saving, which, if successful, will return a select with a new field.
