I'm popping in to add that the Align panel has been modified in the current version. In addition to selecting the Align Bottom button Migintosh pointed out, you also need to choose Align to Selection from the now-hidden menu. InDesign will leave the lowest object in place, and move the ones down that are higher on the page. FYI, if you Align to Top with Align to Selection active, every object moves up to the top-most object on the page. InDesign looks at the selected objects and makes the decision.
Alternatively, you can select the objects you want to align, then click the one that needs to stay still one more time. It will show a thicker blue border and be designated a key object—the key object always stays still and other objects have to align to it.
Thanks for quick replies.
I meant to write "distribute" not "align"
Choosing Align to Key object first and then selecting the bottom box and then Distribute Spacing works fine.
Thank you again,
