If I am not mistaken that appears to be adding an entire group, panel, and panel items (tabs). I need to insert a tab (tab item?) into an existing panel.
For example, in the source you posted the default layoutStructure object array contains a panel with id=”item0′ and a label of “Tabs 0”. It contains an Item with the label “Tab A” that renders as a tab. I need to be able to dynamically add a new item (e.g. “Tab B”) to the existing “item0′ panel such that it displays in the same group/panel as Tab A.
Is this possible to accomplish this in the Blazor version of the control now? If so, how?
