I\'d like to target two divs for expand when clicking on a single trigger? Is that possible?
There is a solution in Bootstrap 4:
Bootstrap 4 documentation: Multiple targets
The least you need is:
data-toggle="collapse" data-target=".multi-collapse"
for the toggle
button class="collapse multi-collapse"
for each element you need to
toggle(While multiple ids in data-target
indeed don't work).
