The conclusion of my thread which you linked to is in my closing post in that thread, which is basically no solution:
Even to this day, in July 2024, I don’t have the functionality I desperately seek (which is really just basic functionality that everybody needs), and I am still unable to update to Bootstrap 5 because the amazing coding work done be @PeteSharp is only compatible with Bootstrap 4.
I’m really quite surprised after all this time no solution has presented itself because one of the most fundamental things we all do on the Internet is linked to things, and yet, we have no means whatsoever to do basic and fundamental linking to tab content in Bootstrap5. Again, super basic stuff here. I just don’t know how to code it myself.
But all this makes me wonder how people can create tabbed content and be satisfied with it if they can’t link to content inside the tab!
Ditto for Accordian content like my FAQ. I can only link people to my FAQ page and not to individual topics within that FAQ because it’s an accordion, and even Pete’s unreleased Bric doesn’t handle that. So to guide people to the right content I basically have to tell visitors to my site that they need to go to the FAQ page and then click on such and such a header to expand it, and after that scroll down and read paragraph number such a such to locate important content. It’s not a good work-around at all, but it’s all I have.
SUMMARY: We desperately need the ability to link/jump to any content with an any Tab or Accordion, even if that content is on another page or the same page.
