How can get the index of the parent and the current node to number such a list? image

minop1205 commented 2 years ago

@zetorby Even if parent index or current index is given to render, it may not be enough to obtain the expected prefix if the tree hierarchy is deep.

In any case, it is necessary to go back to the root node to get the index of each hierarchy, so please implement the logic in your application as shown in the example below.
