Tree component

Hello Radzen team,
What is the purpose of the Leaf property on the Levels?
I assumed if set to Leaf = true the expand icon should not display however that does not appear to be the case as the icon is always displayed even if the node is not expandable.

It seems that PrimeNG stopped looking for true at some point:

github.com

primefaces/primeng/blob/master/src/app/components/tree/tree.ts#L998



isMultipleSelectionMode() {
    return this.selectionMode && this.selectionMode == 'multiple';
}

isCheckboxSelectionMode() {
    return this.selectionMode && this.selectionMode == 'checkbox';
}

isNodeLeaf(node) {
    return node.leaf == false ? false : !(node.children && node.children.length);
}

getRootNode() {
    return this.filteredNodes ? this.filteredNodes : this.value;
}

getTemplateForNode(node: TreeNode): TemplateRef<any> {
    if (this.templateMap)
        return node.type ? this.templateMap[node.type] : this.templateMap['default'];
    else

We will fix our code in the next update.
