Hi Toko,
Sorry for the inconvenience.
We have validated the reported issue at source level deeply and came to the solution that if we want to load accordion items by dynamically we must use the AccordionItemsDirective tag which means if we would use the HTML version for accordion items, we could not support to load the items dynamically. So we suggest you to use the AccordionItemsDirective tag to load the items dynamically in your project like below,
<AccordionComponent ref={acrdn => this.acrdnInstance = acrdn}>
<AccordionItemsDirective>
<AccordionItemDirective header='ASP.NET' content='Microsoft ASP.NET is a set of technologies in the Microsoft .NET Framework for building Web applications and XML Web services.' />
<AccordionItemDirective header='ASP.NET Core' content='ASP.NET Core is a free and open-source web framework, and the next generation of ASP.NET, developed by Microsoft and the community. It is a modular framework that runs on both the full .NET Framework, on Windows, and the cross-platform .NET Core.' />
<AccordionItemDirective header='ASP.NET MVC' content='The Model-View-Controller (MVC) architectural pattern separates an application into three main components: the model, the view, and the controller.' />
</AccordionItemsDirective>
</AccordionComponent>
Kindly try the above sample and revert us for further assistance.
Regards,
Vengatesh.
