Expandable/collapsible scripted fields in Dashboards

[igor m]

We have a scripted field that is expandable/collapsible in filter, but seems like expand/collapse is not working in dashboards using the same filter. is it a bug or it is not supposed to work in dashboards?

simple example, expands in a filter, doesn't in dashboard:

String GetListHtmlOutput() {
    String htmlHeader = ""

    htmlHeader = htmlHeader + """
 <div id="expander-with-replace-text-content" class="aui-expander-content">
What happens when you add a shiny new browser to a stack of already-disagreeing citizens? You’ll inevitably find some bugs. 
</div>
<a id="replace-text-trigger" data-replace-text="Read less" class="aui-expander-trigger" aria-controls="expander-with-replace-text-content">Read more</a>
                                 
        """
    return  htmlHeader
}

GetListHtmlOutput()
