Question

I’ve been trying to remove the icon from a collapsible set by setting the attribute data-iconpos="none" in the div that acts as the collapsible-set, but no luck. It would remove it but still leave some kind of shadow.

Answer 1

The only solution for this is using CSS, try adding a class to the collapsible such as: class='listItemNoIcon'

within your HTML file add this :

<div  class='listItemNoIcon' data-role='collapsible' data-collapsed='false'>
</div>

and add this to your css file:

.listItemNoIcon .ui-icon
{

 display: none;

}
