For our application we what to show actions and messages in HTML. When a message is to long we want to collapse it and give the user the possibility to unfold it manually by clicking on it (see image) and therefore we added some javascript to the HTML.
I have tested this in a form and in a cardlist but it seems the script gets filtered out. Also tested this with a preview-screentype as mentioned in this topic but it seems this is not supported in Universal.
Is there a way to achieve this in Universal?
