How to open up 'Settings' all the time?

You can pass in the property open to your sector definiton.

sectors: [{
            name: 'Typografie',
            open: true,
            ...
}]

@SeongwoonHong That settings panel it's a custom element https://github.com/artf/grapesjs/blob/6cb1199048a753a77466efd4ae8ff3752d413623/demo.html#L1409-L1430 I just append traits there, but the toggle (open/close) is actually a custom thing

@NicoEngler Hi, Thank you but I'm not talking about sector (dimension, typografie etc). I'm talking about 'Settings'.. in other words, if i do editor.StyleManager.getSector('Settings') is null..
