How to uncollapse the first and second tiers of a link tree in JavaScript?

+0
−1

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.

Can you please also provide the HTML / the way it is built dynamically? Currently, the relationship between nodes and their children is not clear and it is needed to be able to go through the descendants and uncollapse through clicking.

Alexei‭ If I understand you correctly than I don't think it's possible to copy the HTML of an entire webpage from DOM and even if it is, the HTML of the entire tree is huge by itself, not something I would want to paste here hence I believe that the link I've putted is the best HTML sharing in this case. Moreover, since it's a link to MediaWiki category tree page it should be stable for the next, about, 25 years at least.

it is needed to be able to go through the descendants and uncollapse through clicking.

That's excatly what I want to do with JavaScript, both totally automatically and brutally (on the entire tree without manually clicking anything).
