Animation using CSS class - html

Question

I have an HTML component which looks like this.
When I add a conditional class to this component two "div"s at the bottom should change its position to the right side of "Primart EMF" text, which looks like this.
I am able to achieve it using display property by changing it from block to inline-block. But this transition is not smooth. I want to add some animation to it, but transition doesn't work on display property.
Can someone please guide me on how to achieve this?
HTML
<ul class="condition-list edit--mode--off"> <!-- edit--mode--off is a dynamic class-->
<li class="condition-element condition-element-selected">
<div class="condition-element-type">Primary EMF</div>
<div class="condition-element-names">
<div class="condition-element-name condition-growth">Innovation</div>
<div class="condition-element-name condition-achievement">Mastery</div>
</div>
</li>
</ul>
CSS
.condition-element-type {
display: inline-block;
max-width: 71px;
margin: 2px 10px 0 0;
}
.condition-element-names {
display: inline-block;
}
.condition-element-name {
display: inline-block;
margin-left: 10px;
border-radius: 8px;
color: $color-white;
font-size: 11px;
margin: 0 8px 8px 0;
height: calc(1em + 5px);
padding: 4px 8px 2px 8px;
margin: -3px 8px 8px 0;
}
.edit--mode--off .condition-element-names {
display: block !important;
margin-top: 5px;
}

Not sure if this is doable as I see only a part of your code, but it is usually more convenient to use transform and transition for smooth transitions. Hope below example helps (click red-bordered buttons to see the transition animation):
document.querySelector('.condition-list').addEventListener('click', function(){this.classList.toggle('edit--mode--off')});
.condition-element-type {
display: inline-block;
max-width: 71px;
margin: 2px 10px 0 0;
}
.condition-element-names {
display: inline-block;
transition: transform .4s ease-out;
}
.condition-element-name {
display: inline-block;
margin-left: 10px;
border-radius: 8px;
color: $color-white;
font-size: 11px;
margin: 0 8px 8px 0;
height: calc(1em + 5px);
padding: 4px 8px 2px 8px;
margin: -3px 8px 8px 0;
border: 1px solid red;
cursor: pointer;
}
.edit--mode--off .condition-element-names {
transform: translate(-100px, 40px);
margin-top: 5px;
}
<ul class="condition-list edit--mode--off">
<!-- edit--mode--off is a dynamic class-->
<li class="condition-element condition-element-selected ">
<div class="condition-element-type">Primary EMF</div>
<div class="condition-element-names">
<div class="condition-element-name condition-growth">Innovation</div>
<div class="condition-element-name condition-achievement">Mastery</div>
</div>
</li>
</ul>
