Update for Org Chart 4.
The code snippet for the Custom JavaScript step:
api.onBoxRendered((box, itemData) => {
let itemWrap = $(box.elem).closest(".poch-group-item");
if (!itemWrap.hasClass("poch-group-item_with-subordinates")) {
$(box.elem).addClass("custom-class");
}
});
Since the HTML structure changed, the box.elem is used instead of the box.elemContainer.
The custom CSS remains the same:
.poch-level-0 .custom-class .poch-toolbar{
display: none;
}
