    I am wondering if there is guidance on editing the Report Viewer template html file. I see the section for the multi-select parameter but if I change it to anything other than a list I get a java script error that "var children = listView.element.children();" saying 
    Uncaught TypeError: Cannot read property 'element' of null "

    I would like to use a multi-select dropdown list instead of just a list, as we have over 100 items in the parameter options.

    Hello Jim,

    The viewer's template files(the HTML, CSS and JS files) generate widgets based on the type of report parameters, which should be visible. You can override the default behavior and specify custom parameters editors, with customized behavior, which will suit your requirements.

    Consider the example in the How To: Create a custom parameter editor article
    . With the given example in the article, it is enough to substitute the name of the widget to kendoMultiSelect to get the new parameter's editor in action.
