I have setup a Joomla with the Corporation quickstart and updated to the neweest Zentools2 plugin.
I have now created a custom module on the front page (at the bottom) which loads a custom module position (history) at which a Zentools2 Accordion is defined which gets its data from a Joomla category and shows title + intro-text.

It should show the first entry by default and correctly does so, however when clicking on another entry or closing/opening it, it will only show the content for a split-second and then close again.
I would appreciate help with this issue as I cannot find what I did wrong.

Link to the page in question: clausel.design4you.lu/
I have added some custom CSS but otherwise left the template untouched.

Is it possible to crop the image above it?

See if that makes any difference to the equal height script

Cheers
Paul
