Hi Artur,
Greetings from Syncfusion support.
Query: “ want to create a DataGrid table with
DropDown Menu like this”
We have checked your shared image and we suspect that you
need to render an Grid and on clicking the menu you should display its
corresponding data under the Grid row. If so we suggest to use detail template
feature of DataGrid. Kindly check the attached documentation for your
reference.
Reference: https://blazor.syncfusion.com/documentation/datagrid/detail-template#rendering-custom-component
https://blazor.syncfusion.com/demos/datagrid/detail-template?theme=bootstrap4

Please let us know if you have any concerns.
Regards,
Monisha
