Path generation
It would be nice to add a path field and implement the generation of the full path to the root element.
Not sure I understand what you mean, sorry. Do you have an example?
This is in Joomla (https://docs.joomla.org/Using_nested_sets). Also used nested sets but also has 2 additional alias and path fields. Example: first level page-id:1 alias:main path:main second level page id:2 alias:child path:main/child And so on.
I may be wrong, but it's like he. https://github.com/joomla/joomla-cms/blob/staging/libraries/src/Table/Nested.php
I've not used Joomla for many, many years I'm afraid. Please feel free to contribute to the code with a PR if you wish to add this functionality.
I certainly try, but I'm afraid my code will be relatively terrible :)
