By default, your "Mode" will be "Multiply". This will change what the shadow will be against in the background: other objects, different colors, different textures, etc. Go through the options and experiment with them.
Let's stay on "Multiply". It is important to note that when an option in a drop-down menu is highlighted in blue, you can press the up and down arrows on the keyboard to go through the options. It will save you some time.
You can change the "Distance", "X Offset", and "Y Offset" values
You can do it by clicking the arrows or typing the number you want. Bear in mind that you don't have to type the "Distance" value in picas. You can use any other measurement units, and InDesign will convert them to picas. It might be a good idea to have a higher distance for the shadow to look more natural.
