We need to provide an option to programmatically customize the expand and collapse actions of the Blazor Dropdown Tree.
Requirement.
In the Blazor Dropdown Tree component, when a new node is expanded, any previously expanded nodes should automatically collapse. To achieve this functionality, it is necessary to provide methods such as CollapseAll, which collapses all expanded nodes, and ExpandAll, which performs the opposite action by expanding all nodes.
To effectively utilize these methods, the NodeCollapse and NodeExpand events should be implemented. These events help manage the state of nodes dynamically by triggering specific actions when a node is collapsed or expanded.
