Hi Jeroen, I think you need to register a custom DM (DataModel)[1] and CE (ContentEditable)[2] node implementation for this extension tag inside VisualEditor to control their rendering and how the user can interact with them. Unfortunately, I am not sure if there is documentation (apart from the generated JSDoc) for these APIs, so I tend to refer to usage patterns in existing extensions when working with them. The Graph extension is an example of an extension that leverages these APIs to customise the behaviour of an extension tag that relies on JS libraries inside the VE.[3]
Hope this helps! — [1] https://doc.wikimedia.org/VisualEditor/master/#!/api/ve.dm.MWExtensionNode [2] https://doc.wikimedia.org/VisualEditor/master/#!/api/ve.ce.MWExtensionNode [3] https://github.com/wikimedia/mediawiki-extensions-Graph/tree/master/modules/ve-graph Cheers, Máté Szabó SOFTWARE ENGINEER Fandom Poland sp. z o.o. z siedzibą w Poznaniu, ul.
