Hi,
I have been developing a custom visual using a HTMLElement object. I have set the <div> to overflow:auto. However, scrollbars do not appear when the content exceeds the iframe bounds. The standard list and matrix custom visuals do exactly what I want but there is no repo for those so I can't learn from that code.
Could anyone please advise how to make scrollbars automatically appear on a custom visual when content exceeds frame size?
