loping through channel entries tag, I can use {title} for the title of the article.
inside the channel entries loop for the specific article, I use an EE partial with get list inside. Inside the list I have a stash var called "title".
{stash:title}{title}{/stash:title}
While using the EE partial, {title} always prints the title of the actual channel entry. While using it not as EE partial, but as an EE embed, the var {title} is choosen from the stash list.
code:
//stash embed which creates the list with related entries
{exp:stash:embed:ech:stash_related_entries stash:entry_id="{entry_id}"}
{exp:channel:entries url_title="{segment:entry}" dynamic="off"}
//display the detail article
//show related article inside the body of the article
{s_showRelatedEntries}
{/exp:channel:entries}
code EE partial:
{exp:stash:parse process="end"}
{exp:stash:get_list name="dataRelated"}
{title}
//HERE prints the title of the detail entry
{/exp:stash:get_list}
{/exp:stash:parse}
