How to do this, but also incorporate a universal toggle at top of page, to expand or collapse all headers?

Total noob, have some ideas, but still a bit unsure on the best approach.
Was going to implement something similar to what's here (also see supplementary page)

Best to show some relevant code and go from there.

Don't have code, best got at this point, is pseudocode...

To further flesh out what was thinking, does this sound about right?
Missing steps or sub-steps? How to further flesh out each step/sub-step?

Each of the collapsible tables should have a class. I’d need to;

1. Create a button in dashboard.ejs that calls a function. This function should:
2. Use a global boolean declared at the start of Dashboard.js to indicate if the tabs should be OPEN or closed
3. Get an array of all of the elements with the above class
4. For each element, check if it is currently open or closed, and simulate a click on the element if I need to change it to match the boolean
5. Change the appearance of the button to indicate what clicking on it should do

(so if clicking on it would expand everything, something like “EXPAND”, or “COLLAPSE” for the opposite)

Create a HTML doc with a <div>, put something in it and post your code.  That's most of us got started.

Essentially, only worked on the dashboard.ejs file - thus far.
But eventually need to do some stuff in dashboard.js, & possibly style.css.
Help, is greatly appreciated....

Thanks again.

Sorry, not going to post same stuff in multiple spots at once, hope folks here aren't pedantic about this sort of thing.
Can always continue our own separate help discussion here, after you've seen what's going on there.

Thanks again.
