There's a ready-made component for it: https://github.com/adem0x/virtualdbtreeex, you can also find it on Online-Package-Manager. See https://forum.lazarus.freepascal.org/index.php/topic,55727.msg415912.html#msg415912 for a demo project.

I checked with Laz 2.0.12 on Win 11. It has a built-in VirtualTreeViews package (needed by the Online-Package-Manager). No problem to add VirtualDBTreeEx. Then I installed the VirtualTreeViews from OPM - again no compilation issue.

Did you try a clean recompilation of the IDE? "Tools" > "Configure Build Lazarus" > in the "Clean up" box, check "Clean all" and "Switch after building to automatically" > "Build".
