    <p>I added a button to the ribbon toolbar button in my extension to the Tridion CMS. On click of the button a popup page will display with two drop downs. By changing the values in the first drop down control I should populate the values for second drop down control. In my case I am using <code>ASP drop down list</code> control. For the time being I will hard code the values to be populated to the second drop down in java script. For this requirement I am using the following code but I am not able to populate the value (Not Identifying the tag).</p> <p>Java script code:</p> <pre><code>ABC.WCMS.RTFExtension.Popups.ButtonPopup.prototype._populate = function () { var selectedValue = $('#functionalcomponent').value;//First dropdown selected value var dropdownId = $("#Dd");//Second Dropdown Control switch (selectedValue) { case "Home Ware": dropdownId.append($("&lt;option&gt; &lt;/option&gt;").val("Select Sub-Category").html("")); dropdownId.append($("&lt;option&gt; &lt;/option&gt;").val("Air-Conditioners/Coolers").html("Air-Conditioners/Coolers")); break; case "Education": dropdownId.append($("&lt;option&gt; &lt;/option&gt;").val("Select Sub-Category").html("")); dropdownId.append($("&lt;option&gt; &lt;/option&gt;").val("Colleges").html("Colleges")); break; default: dropdownId.append($("&lt;option&gt; &lt;/option&gt;").val("Select Sub-Category").html("")); dropdownId.append($("&lt;option&gt; &lt;/option&gt;").val("No Value").html("No Value")); } return true; } </code></pre> <p>ASPX Controls:</p> <pre><code>&lt;%--Dropdown1--%&gt; &lt;asp:DropDownList ID="functionalcomponent" runat="server"&gt;&lt;/asp:DropDownList&gt; &lt;%--Dropdown2--%&gt; &lt;asp:DropDownList ID="Dd" runat="server"&gt;&lt;/asp:DropDownList&gt; </code></pre> <p>How can I populate the values for second drop down from external JavaScript file?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
