Prime Community Forum

I'm new with Prime. I use primevue for my project. To print my product categories and subcategories, I use treetable. When I add new subcategory to a category which doesn't have any child yet, it's perfectly added, but I can't see it immediatly cause expender icon doesn't show itself until after I try to filter or refresh page,

Try to create a new instance of your tree model.

Please see;

Thank you! But I don't know how to do that.
I mean creating new treetable instance

Hi,

You can use vm.$set(vm.items, indexOfItem, newValue) on Vue2. Please examine the shared link for details.
