Conflict with Bootstrap Workaround

I use a theme based on Bootstrap 4 and found that the CSS classes ‘collapsing’ and ‘collapse’ used by the plugin conflict with those from Bootstrap.
The workaround I applied was to modify the plugin code and rename those two classes to avoid the conflict. I did not modify Bootstrap.

The primary effect was that the plugin only displayed the title, due to the fact that ‘collapsing’ from Bootstrap sets height=0.

I am posting this because someone else might have the same issue.
