Hi Ross,
Thanks for using Syncfusion products.
We have prepared a simple sample with Accordion as per the steps suggested in our documentation and we did not face any issue as reported. The sample can be downloaded from the attachment.
We suspect that the reported issue may occur if the namespaces are not added or if the assemblies are not referred, kindly check whether you have added the following lines in your web.config file,
<code>
[Assemblies]
<add assembly="Syncfusion.Core, Version=10.204.0.56, Culture=neutral, PublicKeyToken=632609b4d040f6b4"/>
<add assembly="Syncfusion.Shared.Mvc, Version=10.204.0.56, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89"/>
<add assembly="Syncfusion.Tools.Mvc, Version=10.204.0.56, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89"/>
[Namespaces]
<add namespace="Syncfusion.Mvc.Shared"/>
<add namespace="Syncfusion.Mvc.Tools"/>
[Handlers]
<httpHandlers>
<add verb="GET,HEAD" path="MvcResourceHandler.axd" type="Syncfusion.Mvc.Shared.MvcResourceHandler, Syncfusion.Shared.Mvc, Version=10.204.0.56, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" validate="false"/>
</httpHandlers>
<handlers>
<add verb="GET,HEAD" name="MvcResourceHandler" path="MvcResourceHandler.axd" type="Syncfusion.Mvc.Shared.MvcResourceHandler, Syncfusion.Shared.Mvc, Version=10.204.0.56, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89"/>
</handlers>
</code>
If you creating your application with MVC3 Razor view engine, the following namespaces should also be added in the web.config file within the Views folder
<code>
[Namespaces]
<add namespace="Syncfusion.Mvc.Shared"/>
<add namespace="Syncfusion.Mvc.Tools"/>
</code>
Kindly check the above suggestion and attached sample and let us know if it helps.

Meena
Hi Ross,
Thanks for the update.
We are unable to reproduce the issue in MVC2 too.Accordion is working fine in MVC2. Kindly download the Accordion MVC2 sample from the below link.
Please let us know if you have any other concerns.

Meena
