Hello Tobbe,
We appreciate your interest!
the component supports multiple tasks on one row
We have introduced split tasks in the Pro edition, which is probably the closest feature to what you are looking for. You can check it out here: https://docs.svar.dev/svelte/gantt/samples/#/split-tasks/willow.
However, please note that this feature is about splitting tasks into segments rather than rendering multiple tasks on a single row.
does the component support being hosted in shadowDom
Regarding hosting the component in Shadow DOM, we haven't tried it yet, and your feedback is valuable for further development. We will open an issue so we can experiment with it.
