Example of the work: http://mobile-island.narod.ru/001/001/0039/index.html

HTML, CSS, and Javascript are used to create linked select drop-down lists, without the need for databases. All select lists are set directly in the HTML code, so this method is well suited for working with small amounts of data.

If necessary, you can add new linked drop-down lists <select> of the 2nd level and new items <option>. Change and set your own value= "" values and item names. The added lists will be automatically taken into account when restarting the calculator and their values will be available when calculating the calculator, without the need to edit the javascript code.
