Collapsing Categories empty

I’ve never heard of that kind of plugin, but you may want to post this issue in that plugin’s support forum because it sounds like it’s more related to the plugin. I don’t see how a theme would affect this plugin, but perhaps they might know. If there is something about the theme, pass it on to me and I can perhaps give you a theme based solution via child theme.

I did a search and it might be related to “bootstrap”. It is using term “collapsing” and mixing the code. Could I deactivate bootstrap somehow and is it used in the theme?

I just looked in the bootstrap css file and sure enough that is there, but not required for this theme, including another batch of code. So what I will do is give you a quick solution with some custom CSS to cancel out what is in the bootstrap css.

Is it only the class “collapsing” that is the issue, or is there more such as another class of “collapse”?

Note: It’s going on midnight for me here so if I don’t hear back shortly, I will follow up tomorrow morning.

In the meantime, if it’s just “collapsing” we need to look at, try this custom CSS to cancel out this and see if that helps:

Original:

.collapsing {
  position: relative;
  height: 0;
  overflow: hidden;
  -webkit-transition-property: height, visibility;
  -o-transition-property: height, visibility;
     transition-property: height, visibility;
  -webkit-transition-duration: 0.35s;
  -o-transition-duration: 0.35s;
     transition-duration: 0.35s;
  -webkit-transition-timing-function: ease;
  -o-transition-timing-function: ease;
     transition-timing-function: ease;
}

Do this:

.collapsing {
  position: relative;
  height: auto;
  overflow: visible;
  -webkit-transition-property: none;
  -o-transition-property: none;
     transition-property:  none;
  -webkit-transition-duration: none;
  -o-transition-duration:  none;
     transition-duration:  none;
  -webkit-transition-timing-function:  none;
  -o-transition-timing-function:  none;
     transition-timing-function:  none;
}

On the next update for this theme, I will remove that and some other CSS that is not being used (which I seem to have left that in).
