I have a category descrption in HTML as simple as seen below but i want to keep the "childs" hidden("mother" always visible) and show the childs when an user click on the "mother" then hide the childs again when mother is clicked but the childs are not hidden. I don't want to user Java Script, can it be done with pure CSS?
<a href="">MOTHER CATEGORY <br>
<a href="">Child 1 </a><br>
<a href="">Child 2 </a><br>
<a href="">Child 3 </a><br>
<a href="">Child 4 </a><br>
<a href="">Child 5 </a><br>
<a href="">MOTHER CATEGORY 2<br> (...)
