Hi Drogheda Web Design,
You’ll need to adjust the HTML yourself inside of the ‘text’ tab. I would recommend using SartMatt’s example page as a guidline. He was actually the one who wrote the patch to enable nesting expandable links with in one another:
https://matthieu.sarter.fr/nested-sample/
And accompanying HTML for the example (sorry for the formatting) :
<div class="exp-col-content-holder"><a class="expand-cnt-link" href="#" rel="nofollow">Parent</a>
<div class="hidden-content" style="display: block;">
<div class="exp-col-content-holder"><a class="expand-cnt-link" href="#" rel="nofollow">Child 1</a>
<div class="hidden-content" style="display: block;">
<div class="exp-col-content-holder"><a class="expand-cnt-link" href="#" rel="nofollow">Child of child 1</a>
<div class="hidden-content" style="display: block;">
Child of child 1 content
</div>
</div>
</div>
</div>
<div class="exp-col-content-holder"><a class="expand-cnt-link ecf_closed" href="#" rel="nofollow">Child 2</a>
<div class="hidden-content" style="display: none;">
<div class="exp-col-content-holder"><a class="expand-cnt-link ecf_closed" href="#" rel="nofollow">Child 1 of child 2</a>
<div class="hidden-content" style="display: none;">
Child 1 of child 2 content
</div>
</div>
<div class="exp-col-content-holder"><a class="expand-cnt-link ecf_closed" href="#" rel="nofollow">Child 2 of child 2</a>
<div class="hidden-content" style="display: none;">
Child 2 of child 2 content
</div>
</div>
<div class="exp-col-content-holder"><a class="expand-cnt-link ecf_closed" href="#" rel="nofollow">Child 3 of child 2</a>
<div class="hidden-content" style="display: none;">
Child 3 of child 2 content
</div>
</div>
</div>
</div>
<div class="exp-col-content-holder"><a class="expand-cnt-link ecf_closed" href="#" rel="nofollow">Child 3</a>
<div class="hidden-content" style="display: none;">
Child 3 content
</div>
</div>
</div>
</div>
