How to remove selected value from hierarchy

[kaperusov]

You can add your own id attribute to the <a> element:

<a id="item-33" class="dropdown-item" data-value="4" data-level="3" href="#">White</a>

And use javascript:

const element = document.getElementById('item-33');
element.hidden = true;   // to hide element
element.remove();        // or removed it

Also you can find it via querySelectorAll":

document.querySelectorAll('[data-value]')[3].hidden = true

Why do we need some additional internal functionality to remove elements? Or do you mean the need to delete the entire branch of the hierarchy?
