Automatically resize rofi menu height

I want rofi to automatically resize menu's height to the number of available options. There is an option -lines but with it I could only pass constant number. So for each call I'm forced to execute command twice - to calculate number of lines and to display menu: #!/usr/bin/sh lines=$(my_command | wc -l) my_command | rofi -dmenu -lines "$lines" Is it possible to tell rofi to shrink its menu to the number of available options?
