selecton/src/js/setHidden.js

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

export default function(d, searchTerm, renderFn){
    if(searchTerm && d.selectable){

        var str = renderFn(d);

        var re      = new RegExp(searchTerm, 'gi');
        var matches = str.match(re);

        if(matches){

            d._search_ = str.replace(re, replaceSearchString);

        }else{

            delete d._search_;

        }

        return (str.toLowerCase().indexOf(searchTerm) === -1) || d.selected;
    }

    if(!searchTerm){
        delete d._search_;
        return d.closed;
    }

    return false;
}

function replaceSearchString(string){
    return '<span class="dropdown-list-item-highlighted">' + string + '</span>';
