Unable to highlight with a custom style

[Mirekium]

Hello,

I am trying to customize the highlighting in phylotree.js (v2.x) — whether for internal nodes, leaves, or edges — and specifically to highlight all descendants of an internal node with a particular style (for example, color or dashed lines).

I have tested several methods:

• Setting the selected property on all descendants

• Adding a custom tag (e.g., customStyle = "descendant")

But nothing works: the style does not apply, whether through selected or a custom property used in edge-styler or node-styler.

tree.render({ edge-styler: edgeStyler });`

`// Attempt to mark all descendants from an internal node
tree.selectAllDescendants(selectedNode, true, true)
.forEach(n => n.selected = true); // or n.customStyle = "descendant"

// In my edge-styler
function edgeStylerSelectDesc(dom_element, edge_object) {
if (edge_object && edge_object.target && edge_object.target.selected) {
// or if (edge_object && edge_object.target && edge_object.target.customStyle === "descendant") {
dom_element.attr("stroke", "#1f77b4")
.attr("stroke-width", "3px")
.attr("stroke-dasharray", "10,2");
}
}
tree.render({ edge-styler: edgeStylerSelectDesc});
tree.update();`

Is there a solution or an example to apply a specific style (and not just the native selection) to all descendants of an internal node?

Thank you in advance for any lead or solution!
