I am using bootstrap v4 in my project so I am trying out the flex layout stuff (which has been great so far!), however I am running into an issue where I have a row that I want to toggle open/closed.
Right now I am just toggling between display: none and display: flex;
Here is an example fiddle - https://jsfiddle.net/LL0qnnxm/35/
and my code looks like -
HTML-
<div class="container">
  <div class="refinement-bar-row">
    <div class="row refinement-bar title-bar">
      <div class="col-12 for-you">
        <p class="toggle-refine-bar">
          click me to toggle
        </p>
        text
      </div>
    </div>
    <div class="refinement-bar filters-bar">
      <div class="row">
        <div class="col-12">
          test
        </div>
        <div class="col-12">
          test
        </div>
      </div>
    </div>
  </div>
</div>
CSS:
 .filters-bar {
   display: none;
   margin-top: 2rem;
 }
 .open {
   .filters-bar {
     display: flex;
   }
 }
a little jquery to toggle the open class :
$(".title-bar").click(function() {
  console.log("clicked");
  $('.refinement-bar-row').toggleClass("open");
});
I tried the swapping the CSS like so :
.filters-bar {
   height: 0;
   display: flex;
   margin-top: 2rem;
   transition: all 0.5s;
 }
 .open {
   .filters-bar {
     height: auto;
     display: flex;
   }
 }
but in the "closed" state you can still see the closed drawer. I'm not sure how you are suppose to accomplish this with flex.
Here is a fiddle with the non working height: 0 to height: auto - https://jsfiddle.net/LL0qnnxm/34/
Any ideas how to animate the flex drawer? I am trying to get it to slide down open (and up closed) if this helps. Any tips welcome, thanks for reading!
