hi guys, how can i add dinamically a child in a tab of a vaadin tabs, like in the TreeGrid? Specifically i need to create child when a tab is selected

Here’s an example with two alternative approaches:

        Tabs tabs = new Tabs();
        Tab clickableTab = new Tab("Click this to add a new Tab");
        Tab tabInSelectionEvent = new Tab("Select this to add a new Tab");
        clickableTab.getElement().addEventListener("click", clickEvent -> {
            Tab newTab = new Tab("New " + System.currentTimeMillis());
            tabs.addComponentAtIndex(tabs.indexOf(clickableTab), newTab);
        });
        tabs.addSelectedChangeListener(selectedChangeEvent -> {
            if (tabInSelectionEvent.equals(tabs.getSelectedTab())) {
                Tab newTab = new Tab("New " + System.currentTimeMillis());
                tabs.addComponentAtIndex(tabs.indexOf(tabInSelectionEvent), newTab);
            }
        });
        tabs.add(clickableTab, tabInSelectionEvent);
        add(tabs);
