== Pipe menus ==
Openbox has a dynamic menu system that uses "[[pipe (computing)|pipe]] menus".<ref name="lxf103" /><ref>{{cite web|url=http://openbox.org/wiki/Openbox:Pipemenus|title=Openbox Wiki:Pipe menus}}</ref> A menu item in a piped menu system can accept the [[standard output]] of a [[shell script]] (or other executable) in order to generate a sub-menu. Because the script runs every time the pointer activates it, and because the script can assess environmental conditions, piped menus enable [[conditional branching]] to be built into the menu system.{{Citation needed|date=September 2018}} A static menu system as used on most window managers gets its layout once, when the window manager is restarted, and will not have the ability to modify the menu layout depending on environmental factors.{{Citation needed|date=September 2018}}
