![]() To do that, we can use the CSS display property to either show or hide a given node. Node filtering is best achieved using a combination of TypeScript code and template conditions rather than mutating the underlying data structure. To achieve both the above ends, we will refactor the Nested Multi-select Tree Demo from the aforementioned article by adding a Show Selected Items toggle control as well as a Filter textbox. As we will see in today’s article, that same method can help us filter nodes based on a number of conditions in order to limit visible nodes to those which are: As part of that web development tutorial, we learned how to retrieve selected nodes using the NestedTreeControl’s getDescendants() method. In the 2nd installment of the Create a Nested Multi-select Tree with in Angular series, we utilized the MatTree to create an alternative to the HTML SELECT control that is better suited for working with hierarchical data. Not only can it represent a variable number of levels, but each item in the tree can possess a different number of children and levels.
