Accordion Collapse

I am new to Wappler & still learning languages, please excuse me If I missed a rule about posting.

Currently playing with adding accordion into my container. All is great, they expand, but when I click on the button expecting them to collapse again, they do not, especially the last one that was expanded. I have done some googling and research but see no clear ay to accomplish this. Is there a resource or guide on this that I missed when researching?
