How to set an ID for an element in Bitrix?

Question

1C-Bitrix

Hello.

I can't figure out how to add an ID and other attributes to the link. You need to add to the link such values ​​as id="cases_send" data-toggle="modal" data-target="#sidebar-popup"

From the documentation I understood how to add an address, a name to the link, but I did not find how the id and attributes.

Here is the link text and address:
"LINK_NAME" => "Contact us",
"LINK_URL" => "#",
"LINK_ID" => "1" //Something like this I mean should be.

Thank you.

in a template also you add, what for parameters?
if you need a parameter, then first you add your parameter to .parameters.php and in the template you display this parameter as a link
