Category-tree needs to load in parts (AJAX?)
0%
Description
We have a wide category-tree with around 6 levels of hierarchy and summing up to around 40.000 entries at the moment. This leads to performance-problems with various brokers (loading stalls until browser-timeout, ...). This could be solved if for example only the next level would be loaded at one time but not all subtrees at once. If you then open a collapsed branch that would load more data via AJAX.

Can the current tree (ExtJS afaik) load data via AJAX when you expand the tree? Is that functionality maybe in use already in other parts of TYPO3, for a similar solution?

the current implementation can't handle ajax requests.
it is also slow because all records are fetched twice. first because of the implemtantion as a normal list for select boxes and then the renderMode tree kicks in and loads everything again using parentId/childId queries to get the tree.

Filed the speed-issue for initialisation you mentioned into a separate issue, since that might be easier to solve imho. #57193
