I am currently using Tigra Tree v1.1 at work.
I was wondering if it could be configured to have an "Expand All" feature.
Does v2.0 have this feature and if so how hard would it be to update to v2.0?
Looks like you've got Tigra Tree Menu PRO control.
Please find sampels of open tree API section Expand/Collapse All functions.
These functions work correctly in both versions.
