How to scroll to selected node in PrimeNG Tree

Question

I have a page with PrimeNG tree and an autocomplete field. My requirement is Tree should be expanded to the matching node when user enters and selects a text in autocomplete field and also it should scroll to the matching node and highlight the node. I tried to expand the tree by setting 'expanded' property to 'true'. But I am not finding a way to scroll to selected node. Any help on this is appreciated. Also please let me know if there is any method that expands the tree using selected node.

Probably not the most beautiful solution, but you can achieve this by using the following util method. public scrollToSelectionPrimeNgDataTable(table: DataTable, element: HTMLElement) { if (table.selection !== null && table.value !== null) { let index = table.value.indexOf(table.selection); let list = document.querySelectorAll('tr'); if (list !== null && index < list.length) { let targetElement = list.item(index); targetElement.scrollIntoView() } } } To use this Method you have to pass a reference of the DataTable and the table itself as HTMLElement to the method. You can get both by using Angular2's @ViewChild decorator.
