Create an multi-dimensional array from objects in localStorage?

Hi all,

This is a bit beyond my JS know how, I have a shortlisting feature on a website that is seemingly working OK at the moment, however, I would like to list out the items under specific headings should they match a specific category.

It may help to have a peek at the site were this is all going on - Watson Memorials

I am using the following JS to loop the localStorage

      Object.keys(localStorage).forEach(function(key){

        var openLargeCol = '<div class="col-12 col-sm-12 col-md-6 col-lg-6 mb-5">';
        var openCol = '<div class="col-12 col-sm-6 col-md-6 col-lg-4 mb-5">';
        var closeCol = '</div>';

        if ( key.match('^K_') ) {
          $('#shortlist-container > .row').prepend( openLargeCol + localStorage.getItem(key) + closeCol );
        } else {
          $('#shortlist-container > .row').prepend( openCol + localStorage.getItem(key) + closeCol );
        }

      });

The key comes from the items id="" attribute, they are prefixed with short letter codes for each type of memorial on show, this should help sort them.

As I say the end goal is to loop through localStorage and spit out items under relevant headings rather than just in the order they were added.

Any help will be much appreciated!
