@viebel yes, using code directly also does not render correctly. My assumption is that the sectionx plugin is hiding the klipse code before it has a chance to render. Expanding the section does not cause an event to tell klipse to re-render. However, resizing the page does trigger the klipse section to re-render and if the sectionx section is expanded then it does not interfere with the klipse rendering.

For now I am just using static clojure code in the sectionx collapsed sections, which is a workable approach (as it will stop the students changing the answers by misktake)

ok

let me now if you need further help @jr0cket
