onHeaderClicked with dataTarget on the Collapse webcomponent

[bodnarescu.diana]

Hello,

The onHeaderClicked event of the servoyextra collapse webcomponent has a parameter: dataTarget.
I thought i can use the data-target in the headerHtml of the collapsible, but it seems there it sanitizes the html: the data-target attribute is removed.

I want to add an icon next to text, in the headerHTML of the collapsible, and execute a specific action when clicking on that icon. Is there a way to do this?

Thank you,
Diana
