Hello,

In this case I would recommend you to take a look for example at the following file:
\CMSModules\Categories\Controls\Categories.ascx or
\CMSModules\MediaLibrary\Controls\MediaLibrary\FolderActions\EditFolder.ascx

Where you will find the code of real usage of this control:

<cms:JQueryTabContainer ID="pnlTabs" runat="server" CssClass="Dialog_Tabs LightTabs BreadTabs">
	<cms:JQueryTab ID="tabCategories" runat="server">
		<ContentTemplate>
			<div class="PageContent">
				... some content
			</div>
		</ContentTemplate>
	</cms:JQueryTab>
	<cms:JQueryTab ID="tabGeneral" runat="server">
		<ContentTemplate>
			... some control
		</ContentTemplate>
	</cms:JQueryTab>
	<cms:JQueryTab ID="tabDocuments" runat="server">
		<ContentTemplate>
			<div class="HeaderSeparator">
				 </div>
			<div class="PageContent">
				... multiple contents... etc
			</div>
		</ContentTemplate>
	</cms:JQueryTab>
</cms:JQueryTabContainer>

JQueryTabContainer control consists of separated JQueryTab elements which have ContentTemplate and in this template you can use the regular CMS, ASP and HTML elements/controls.
