Native cascading drop-down lists
Cascading drop-down lists with filter should be a native extension to the SharePoint List Lookup field type by now. Considering the universal applicability of this type of operation, it's shameful that it has been overlooked yet again in the modern list UI.
I have yet to build a non-trivial list in SP that doesn't require this. The current workarounds are cumbersome and nearly impossible to maintain.
Come on Microsoft - this has been a problem since SharePoint was introduced. With SPO, we no longer have the capability to work around this without using PowerApps - not an option in our SPO tenancy as it has been effectively disabled.
Isn't it about time you got this fixed? It should be a native column type in Lists.
