Hi @bloke! Our tabbed content block supports this feature via the Tab Anchors feature in the inspector toolbar. Simply select the tab that you want to be opened via Tab Anchors and enter the anchor name you want to use with it. To check if it works, go to the page where the tabbed content is used (either saved or preview versions) and add a number sign followed by the anchor’s name (e.g. #targettab) to the end of the URL. The tab that would match the anchor should automatically open.
Please let us know how it goes.
