Implement a global "expand/collapse elements" button

Implements #6025

What I have not figured out yet (and could not find any useful resources on the internet) was how to efficiently localize the controller. Passing 6 labels on ever instantiation feels wrong to me, but having a global array feels wrong too 🤷 any ideas?

I'd just output the labels as JSON in an additional data attribute.

I'd just output the labels as JSON in an additional data attribute.

but this would output the labels for every data-controller again and again?

[fritzmg]

Which is good enough, since there will likely only be one toggle button per back end response, or won't there?

[aschempp]

no, the controller is on every content element that implements the dynamic height property. It dynamically generates the global toggle operation on the fly.

[aschempp]

I have rewritten the whole controller script and approach. Instead of setting a limit_height (and corresponding height class) in your custom row callback, you can now set a list.sorting.limitHeight property on the DCA, and it will automatically generate the necessary operation and wrapper DIVs in DC_Table 😎

Thank you @aschempp.
