The easiest way is to select the layer you want to crop from, and then use the keyboard shortcut Command+J (PC: Ctrl+J) to cut the layer off at the bottom. If you want to crop multiple layers, you can use the Lasso tool to select the layers you want to cut, and then use the keyboard shortcut Command+J (PC: Ctrl+J) to cut them all off at the bottom. You can also use the Crop tool in Photoshop to crop only one layer by clicking on the cropping border around the edge of the layer, and then using either of these methods to cut it off at the bottom. ..
