Hello there! Right now, the Popup doesn't have that set you want. So you need to costumize.

Have a look at this component! 

https://www.outsystems.com/forge/component-overview/9972/hi-element-scroll

You can see at the end of the demo screen you can see a button to open a popup that has the component to give the scroll

Or...

you can use the max-height: 'choose the height' and the overflow-y: scroll to trigger the scroll. on the element, you want to give the scroll.

Kind Regards,

Márcio

Hi Gleb,

The component suggested by Marcio should do the job however a simple alternative solution would be creating a css class with the following properties: 

.scrollable-container {
   height: 300px; //Could be set to whatever height you are after
   overflow-y: auto;
}

You can then assign the scrollable-container class to your container (by replacing "overflow-y: auto;" with "scrollable-container" in your screenshot)

I know I'm late to the party, but if anyone else has this issue I was able to achieve that effect for all popups with this CSS:

.popup-dialog {

     display: flex;

}

.popup-content {

     overflow-y: auto;

     width: 500px;

}

If you only want some popups to behave in this way, you could apply a custom class, and constrain the CSS selectors accordingly.
