To bind an event to a treeview node in Vuetify, you can use the @click event listener on the <v-treeview> component and access the node data using the item argument in the event handler. This allows you to perform actions based on the clicked treeview node, such as opening a modal, navigating to a different page, or updating the node's state. Additionally, you can customize the appearance or behavior of the treeview nodes using Vuetify's extensive styling and configuration options.
