Scroll bar is not working on mesh

i used normal scroll bar. i place it on mesh. but it worked on full ui but not on mesh

Hello and welcome to the forum !!!

I am not sure to fully understand the question. Could you reproduce the issue in the playground ?

Thanks a lot.

mouse scroller is not working . i have to click the bar to scroll.

Yup, but would still be amazing to have an example in the playground to simplify the work of the community in trying to help you.

Is it possible to create a simple repro ?
