prevent expanding collapsible when delete btn is clicked in materialize css

Question

I am using materialize collapsible for showing the list items. And I have two buttons, one for expanding the collapsible and the other for deleting the list,

Expanding the list works fine, but when delete button is clicked I ask for confirmation for deleting the list, if "yes" it will be deleted otherwise wont be deleted.

So the actual problem I am facing is when click the delete button, the confirmation pops up, and when I click "no" the list is expanding. I need to prevent this behaviour.

I am attaching the link :
