how to send an object behind another object

[fmpfmpf]

i created many LED lights on the front panel.

Then i create a platform.

The problem now is, when i drag the LEDs to the platform, the platform covers the LEDs. How can i push the platform behind the LEDs without redrawing everything?

TQ

Use the move options in the grouping button.  It's the black arrows button up near the font selector on your menu bar.
