How to make a Rofi button widget execute a shell command?

[Ali-v1074]

Hi everyone!

I've been working on recreating the Windows 11 Start Menu style in Rofi, and I'm really happy with how it turned out! I managed to get the layout, icons, search bar, and overall look working great.

However, I'm stuck on one last thing — I added a power button at the bottom right of the menu, but I can't figure out how to make it actually execute a command (like opening a power menu or running a shutdown script) when clicked.

From what I've researched, Rofi's button widget supports the action property, but it only accepts keybindings, not shell commands directly.

Does anyone experienced with Rofi know how to make a clickable button execute an external command or script? Any help would be greatly appreciated!

Here's a screenshot of my current design:

Rofi theme button { action: ... } cannot execute a shell command directly.
It can only trigger a rofi keybinding action, as you said.

How about using a wrapper script:

button-power {
    text: "⏻";
    action: "kb-custom-1";
}

Then run rofi from shell and check the exit code.
For dmenu, custom keybindings return exit codes 10-28, so kb-custom-1 is 10.

rofi -show drun -theme your-theme.rasi
case "$?" in
    10) ~/setting/script/rofi-power-menu.sh ;;
esac

I did exactly that, but the button didn't work. So I ran this command:

rofi -show drun -theme ~/.config/rofi/style.rasi; echo "Exit code: $?"

But when I clicked the button, nothing showed up at all.
