Set multiple parameters in one go with Attribute Splatting

Sometimes you don’t want (or need) to handle every parameter explicitly.

You can use a Dictionary to capture any arbitrary attributes someone might try to set on your component, then ‘splat’ those into another component

For example, an ImportantPanel component which delegates to a Panel component…

<Panel @attributes="Attributes"
       EmphasisColor="#FF0004"/>

@code {

   [Parameter(CaptureUnmatchedValues = true)]
   public Dictionary<string, object>
          Attributes { get; set; }

}
