I have the following Stash variable list to get the related author of an article
{exp:stash:set_list name="my_list" parse_tags="yes" parse_depth="2"}
{exp:playa:children var_prefix="children" entry_id="{entry_id}"}
{stash:author_name}{children:title}{/stash:author_name}
{stash:author_bio}{children:profile_bio}{/stash:author_bio}
{stash:item_entry_id}{children:entry_id}{/stash:item_entry_id}
{exp:stash:set_list:nested name="related_entries" context="{children:entry_id}" parse_tags="yes"}
{!-- Matrix tag pair --}
{profile_social_media}
{stash:related_title}{url}{/stash:related_title}
{/profile_social_media}
{/exp:stash:set_list:nested}
{/exp:playa:children}
{/exp:stash:set_list}
but struggling to then get the social media profiles contained within a Matrix field for that related author.
Then in the wrapper we have
{exp:stash:get_list name="my_list"}
<div class="{switch='row|rowAlt'}">
<h1>{author_name} (item {count} of {absolute_results})</h1>
{author_bio}
{exp:stash:get_list:nested name="related_entries" context="{item_entry_id}" prefix="nested"}
<div class="{nested:switch='row|rowAlt'}">
{related_title} (Related item {nested:count} of {nested:absolute_results})
</div>
{/exp:stash:get_list:nested}
</div>
{/exp:stash:get_list}
Author name and bio are fine, just not the Matrix rows.
