Client wants a blog archive with the posts inside accordions whose toggle is the year. Two example years HTML below.

I have the individual fields exposed as tokens within my view with no problem. What I can't see how to do is to enable conditional logic so I express the Year toggle structure once per year of posts.

Is this possible with a View?

I went over Blog monthly archive block - list of posts grouped by year then month I read the 10 year old post at http://chrisshattuck.com/blog/how-create-monthly-archive-block-drupal-blog-views

I have a working view Block but not nesting the way I need it. It outputs a whole accordion per post (as I knew it would).

<div class="fcx-accordion" id="accordion">

<h4 class="fcx-toggle"><a data-toggle="collapse" href="#list2019">2019</a></h4>
<div class="panel">
    <div class="accordion-content panel-collapse collapse" id="list2019">

        <ul>
            <li>{Authored on} - {Linked title}</li>
        </ul>

    </div>
    <!-- accordion-content -->
</div>
<!-- panel-->
<h4 class="fcx-toggle"><a data-toggle="collapse" href="#list2018">2018</a></h4>
<div class="panel">
    <div class="accordion-content panel-collapse collapse" id="list2018">

        <ul>
            <li>{Authored on} - {Linked title}</li>
        </ul>

    </div>
    <!-- accordion-content -->
</div>
<!-- panel-->
