Unable to see checkboxes from topcoat theme

What sdk version and target apllication are you using? This problem may be related to incompatibility of modern css templates, with old CEF versions, that illustrator use. You can try to use some css autoprefixer loader, if you are using module bunling system in your project, or just try to prefix your topcoat css files.

I found out that you have to use the topcoat html code for a checkbox or any element that doesn't show up.

i.e.

HTML

<label class="topcoat-checkbox">
 <input type="checkbox"> 
<div class="topcoat-checkbox__checkmark">
</div> Default
 </label>
 <br> 
<br> 
<label class="topcoat-checkbox"> 
<input type="checkbox" disabled> 
<div class="topcoat-checkbox__checkmark">
</div> Disabled 
</label>

still checkmarks are not showing up when i click the enables one
