The Native Blazor Report Viewer uses Blazor Multiselect by default for multiselect parameters. This becomes very cluttered when many items are selected.
I want to display parameters in a multi-select dropdown list with check boxes, exactly like this: https://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/checkboxes/defaultcs.aspx
The equivalent Blazor demo is more cluttered as selections showing in the select box: https://www.telerik.com/blazor-ui/documentation/knowledge-base/multiselect-checkbox-in-dropdown
The article here https://docs.telerik.com/reporting/embedding-reports/display-reports-in-applications/web-application/native-blazor-report-viewer/customizing/how-to-create-custom-parameter-editors has an example on how to customize the parameter widget in Native Blazor Report Viewer.
Can anyone here share the code to create a nice clean multi-select dropdown list with check boxes for a parameter in the Native Blazor Report Viewer?
