Tree - Expand All/ Collapse All - Performance Issue

[parthibansekar87]

Hello all,

We have a huge sized tree in our application and the Expand All/ Collapse All, implemented as in the example (here - https://www.primefaces.org/primeng/#/tree), take a lot of time to complete the action. Also, I am unable to add any spinner or loader (even if I add, they don't appear) when this is in progress. The screen goes inactive till this completes and sometimes the browser crashes if the user impatiently keeps clicking on the progress. Can anyone advice on the same, please?

Thanks, PS
