Hello @szuwar,
You also sent us a message via a contact form on our website, but after I replied there was no follow-up from your side, so I’m reposting the reply here.
Before we change the code, may I ask why you need a fixed id?
The reason I ask is that if you need the id to run your custom js function, you can do it with the onclick shortcode parameter.
Onclick JS function:
onclick=”your custom JS function name or inline js, e.g. alert(‘Hello World!’); ”
Pls let me know if you need fixed id for anything else.
