Custom visual using drop down (sandbox)

akkadak — Wed, 19 Jul 2017 17:09:00 GMT

Dear all,

I am creating a custom visual which is a dropdown. As I am developing using the Power BI sandbox mode the visual is in an Iframe and therefore impossible to make the dropdown go past its Iframe. Therefore all overflow is hidden.

What is the best way to achive this?

Thanks,
Arnor

Hello @akkadak,

There's no way to go out of sandbox element. I suppose that you should specify a minimum height for the visual in order to be able to open a dropdown.

@akkadak,

In addition, use the CSS overflow property.

The trick was to adjust the height of the sandbox element to accomodate for the height of the dropdown. Then make the background transparent or remove it all together. Then use custom css styling to "fake" the desired effect.
