How to select multiple nodes in the tunimtreemenu component, with a check box?

[Hunter]

I did not find the multi-choice property in the tunimtreemenu component. I tried to modify the imageindex property of the node in the code, but an error was reported
:_snatr_is_not defined.thanks!

I uses 1.90.0 build 1535.

Hello,

Can you make a simple testcase?

And if you add this function?:
