Hide overflow from container

[Guarana]

Hi,

is there any type of container in phaser where I can define its width and height and then hide all overflow of it?

I want to create a sprite slider which sits on a white rectangle.

But currently all items that exceed the bounds of the rectangle are visible and I havent found a solution to hide them.

I've seen the BitmapData alpha mask example but wont it have a huge impact on performance?

And can I interact with sprites (Click, Drag) when they are part of BitmapData?

Just use a rectangular mask, look at this for the basic creation method:
