Introduction

In this article, we will show you how to make a nested datalist to expand in an iframe.

Implementation

You can use the following script in a custom HTML field in a form and alter the code based on your app.

<iframe name='iframe' id="iframeLoanedItems" src="/jw/web/userview/kb_nestedDatalistIFrame/v/_/basicForm_crud?embed=true" frameborder="0" border="0" cellspacing="0" height="500px" scrolling="yes" style="border-style: none;width: 100%"></iframe>
<script>
    $(document).ready(function(){
        $('iframe#iframeLoanedItems').load(function(){
            $('.nesteddl_trigger', $('iframe#iframeLoanedItems').contents()).trigger('click');
        })
    })
</script>


To embed a list inside an iframe you will need to use the <iframe> attribute and target the Menu ID containing the list. In this case "basicForm_crud" is the targeted Menu.

Figure 1: Targeted Menu ID


embed=true

Do take note "embed=true" is important. If not inserted in src, the whole targeted page will be displayed in the iframe instead of the List only.
