QTree Behavior

spyke113

Hello, can I get QTree behavior like Vuetify Treeview when I select “Activatable” and “Open on any item click” at the same time?

So you want to be able to select the leaves of the tree (which is called “activate” in Vuetify) and also toggle the expansion state when a node is clicked?

<q-tree
      :nodes="nodes"
      node-key="key"
      :expanded.sync="expandedNodeKeys"
      :selected.sync="selectedNodeKey"
 />

data() {
   return {
      expandedNodeKeys: [],
      selectedNodeKey: null
   };
},
watch: {
   selectedNodeKey(value) {
      if (value) {
        if (this.expandedNodeKeys.includes(value)) {
          this.expandedNodeKeys = this.expandedNodeKeys.filter(x => x !== value);
        } else {
          this.expandedNodeKeys.push(value);
        }
      }
      // TODO: check if the selected node has children and if so, set this.selectedNodeKey to null
      // that effectively makes only the leaves of the tree selecteable
    }
}
