Auto-collapse not working for multiple posts on homepage

The problem is that you are using the same id for each set, ie: details. ID’s should be unique for each element, so rename your id’s: details_book1, details_book02 and so on.

Regarding your css, rather than use the id to define the css, use the trigclass class like so:

[expand title="My Title" id="example_01 trigclass="my_class""]This is my content [/expand]

Then in the custom style section:
.my_class { background-color: red; height: 50px; }

Hope this points you in the right direction!

You are absolutely correct. It didn’t occur to me to utilize the trigclass instead. Thanks for the clarification and feel free to resolve this ticket. Thanks again!

Glad everything worked out. Don’t forget to vote for Pedro!
