Collapse Component - MDB 5 Pro Essential - Material Design for Bootstrap

Topic: Collapse Component - MDB 5 Pro Essential

Question from the following pagehttps://mdbootstrap.com/docs/b5/angular/components/collapse/#docsTabsOverview

See attached screenshot of code. In the documentation, it does say we can target using "data-mdb-target", but the only way to get the collapse to work, is using the click with the toggle function. Is this documentation out of date?

Also, I assume the expectation would be similar to regular bootstrap in that on click, the button state change to aria-expanded and class would change. Currently, this does not work as well

The working example does seem to do that, but not sure why putting that in my project, does not work

Thanks

@SSNCBarracoders This description is incorrect, thank you for letting us know about this problem. You should use the Angular template reference variable (#variable) like in the code we added in the snippet below.

Did you forgot to add the snippet or referencing what is on the current collapse example?

thanks. Unfortunately, it looks like the new code took a step back in regards to accessibility as the collapse now does not update the aria-expanded when toggled nor does it add the "collapsed" class as it did in previous versions. Will need to figure out a different solution as accessibility is part of what we add to our applications.

Seems accordion is up to date, but collapse still needs some work

@SSNCBarracoders I added that to our to-do list and we will take a closer look at this problem.
