Grapesjs requires your commands to have the run and stop functions for them to toggle panel buttons automatically, so maybe that might be the issue:
const cm = editor.Commands;
// grapesjs unable to toggle panel buttons on this command format
cm.add('desktop', e => e.setDevice('Desktop'))
// grapesjs able to toggle panel buttons because of run and stop
cm.add('desktop', {
run(e) {
e.setDevice('Desktop')
},
stop() {}
});

Thank you for that. Active state is now working for me when creating devices-c panel through grapesjs.init().
const editor = grapesjs.init({
panels: {
defaults : [{
id: 'devices-c', // Responsive view controls
appendTo: '.gjs-toolbar-responsive-views',
buttons: [
{ id: "set-device-desktop", command: { run(e) { e.setDevice('Desktop') }, stop() {}}, className: "fa fa-desktop", active: 1},
{ id: "set-device-tablet", command: { run(e) { e.setDevice('Tablet') }, stop() {}}, className: "fa fa-tablet" },
{ id: "set-device-mobile", command: { run(e) { e.setDevice('Mobile portrait') }, stop() {}}, className: "fa fa-mobile" }
]
}]
}
});
Thanks for reporting this, @RaresVlaiduc.
The issue with (v0.16.41) Button not set as active on click appears to be a race condition or state management timing problem. This typically happens when component lifecycle events and DOM modifications overlap, creating an inconsistent state.
What to try:
- Add a setTimeout wrapper to ensure the DOM has settled:
setTimeout(() => {
// your operation here
}, 0);
-
Check initialization order — make sure components are fully loaded before you interact with them
-
Use the editor's event system — listen to completion events:
editor.on('component:mount', (component) => {
// safe to interact with component here
});
Recommended next steps:
- Test with the latest GrapesJS version if you haven't
- Provide a minimal reproducible example (CodeSandbox) — this helps the team identify the root cause faster
- Include GrapesJS version, browser, and console errors in your report
