How to uncollapse the first and second tiers of a link tree in JavaScript?
I wish to display the first and second branches of a link tree with JavaScript.
I want to show these branches in a single action, instead of clicking each vertical arrow (link) anew.
As can be read in the linked webpage, one can click the vertical arrow to get the next branch (if there is one).
Code which I have tried and failed
document.querySelectorAll(".CategoryTreeToggle").forEach( (element)=>{
if (element.hasAttribute('data-ct-state', 'collapsed') ) {
element.click();
}
});
For some reason, with the following code, all branches, whether collapsed or manually expanded, will collapse.

The first item your selector returns is the top level arrow. hasAttribute just tells us if the attribute is present, not what the value is. So basically your condition is returning true for all elements. Since that includes the top level element, it gets clicked and everything collapses.
Try:
document.querySelectorAll(".CategoryTreeToggle").forEach( (element)=>{
if (element.getAttribute('data-ct-state') === 'collapsed' ) {
element.click();
}
});
