Hey I don't mean to nag at all just wondering if there is an update.

You could try placing the List in a Grid component with only 1 row and 1 column, this would put a box on the screen.
Then in the properties tab assign the width and height in pixels (px).
You will have to play with it to find out how many pixels you would need, but if you already know the size of the popup then you are good to go.

assign your CSS to apply to the grid instead of the list.
Apperyio('MobileGrid').css('overflow') == 'scroll'

Would I just run this on page show or load?

Apperyio('MobileGrid').css('overflow') == 'scroll'

I would do it on page load. also make sure you change "MobileGrid" to the name of the grid on the page.

Ok so when I put that code in the editor, errors come back and because of my inexperience, I don't know what they mean. Did I do something wrong?

Change this,
Apperyio('mobilegrid_107').css('overflow') == 'scroll';

To this,
Apperyio('mobilegrid_107').css('overflow' == 'scroll');

I don't get any errors when I try it.

I no longer get errors but unfortunately, it doesn't work. It is like the grid won't stay the size that I assigned the dimensions to be. I set the grid and the cell to the specific size and they still change sizes.

Could I try putting the code in the mapping somewhere or something?

perhaps somebody else could chime in and help you out.

the only Idea I have left would be to set the width to auto and only set the height to what you want. I'm not that great with CSS.

Thanks for your help so far. I too would like it if someone could chime in.
