selecton/src/js/openAllParents.js

Selecton.js combines a searchbar and a dropdown menu with nested child lists.

import {_getDropdownListitems} from './elementHandler';

export default function(w, p, key){
    openAllParents(w, p, key);
}

function openAllParents(w, p, key){
    if(p !== 'root'){
        var f = _getDropdownListitems(w).filter(function(d){ return key(d) === p; }).data()[0];
        f.closed = false;
        f.children.forEach(function(d){ d.closed = false; });
        openAllParents(w, f._parent_, key);
    }
}
