Hi Friends,

I am working on node red and stuck with one problem.

How can we control the list of node (letf panel node) dynamically. Depending upon query string parameter i have to load only specific node on left side. Is there any way.

I can see red.min.js has function "loadNodeCatalogs" and tried to apply some condition, but it is not working.

Thanks  
Shrwan

Has anyone solved this need? This would be extremely useful in multiple enterprise scenarios including RBAC.  
You may want to control nodes and flows accessible based on one's role.
