Thank you for providing this idea. Could you clarify what exactly you're looking to achieve with this idea. We're working on some changes to support 320px width publish to web reports so they look good on a small phone. Some more details on your idea will help us understand if this is what you're looking for or if it's something else entirely.
Hi everyone. We’re making progress! We just shipped a dropdown slicer in our November update: https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-november-feature-summary/
The other features requested here (multiple fields, one and only one value, relative date ranges etc.) are still being considered. We’ll keep working on them and will update you again as these features are finished!
Thanks again for your support!
We have a custom visual that allows much more capabilities than the built-in slicer. It provides many formatting properties that make it a charm to use.
You can find it here:
Let us know if this is along the lines of what you need or how we can enhance it.
Have you taken a look at our report embedding APIs: http://blogs.msdn.com/b/powerbidev/archive/2015/09/23/power-bi-api-updates-roundup.aspx ? Those will work in an ASP.NET MVC app. Let us know more details on what you'd like 'MVC' support to look like.
