The problem is in 40 41 44 45 lines.
I was asked the following: so that when introducing string data (string) into objects of type int, an error does not occur, but there is a conversion.

Answer 1

no way, even if you insert it into the option, it will not be displayed in the select, only plugins, only hardcore)

Answer 2

No way. The logic of such selects is to hide the standard select and draw your own on a div or ul > li. When choosing, change the custom and standard select. It is best to write a plugin with API methods (get, set ...) or use a ready-made one.

Answer 3

No way, make it custom. The select cannot be customized since it is drawn by the OS and not by the browser.

Answer 4

I apologize, out of habit, after 15 minutes of searching on Google, I'm posting a question here, I decided to make it normal labels.

Answer 5

int.TryParse()
