TreePanel Nodes with filtered Children

Question

I have a TreePanel. When I filter the store of the TreePanel so that a node appears to be empty, the symbol to open the node is still there. I think it would be better if the symbol to open the folder disappeared if its content is not visible. Is there a solution for this?

Answer 1

You can set "expandable: false" on the filtered and empty nodes (children:[]) and do the same thing when inserting new code.

Answer 2

The icon is rendered if the node's isExpandable function returns true. You can override that function to your needs.

Or maybe you want to override the hasChildNodes function to include a check whether the child nodes are filtered out or not.
