title: Expand div in a grid thumbnail with jquery
body: <p>how to make the ul li grid expanded like this picture below ></p>
  
  <p><img src="https://i.stack.imgur.com/d4PKS.png" alt="enter image description here"></p>
  
  <p>i mean, when i click each of the thumbnail, the bigger box will expanded below them ( each thumbnail that clicked ), if possible like toggle or slide up / down effect</p>
  
  <p>it's more like google image function, but i just need the proper way to expand a box in grid, without plugins</p>
  
  <p>Thanks</p>
