Can you please clarify what you mean by "prest" in this context?

[vuejspyf]

It seems to be a specific term or function that you want to use to switch between objects. Once you provide more information about "prest" and the platform or programming language you are using, I can assist you further in implementing the functionality to load and switch between multiple objects.

i have may level(obj) to show

As per my data structure, I need to load multiple objects. How can I achieve this? I have been trying for a long time but haven't been successful. It is possible that there is already an API for this, but I might have missed it. If not, could this functionality be added? Thank you very much.

i want

Click to toggle objects (levels) in the dropdown menu. Click 'New' to create a new object .

thank u very much

[vuejspyf]

click the "Default”button to change(switch) object ,click "New button to create Object

[vuejspyf]

I already know how to do it,Thanks

let levelInfo = {};
for (let index = 0; index < dataJson.levellist.length; index++) {
const element = dataJson.levellist[index];
levelInfo[levelArr[index]] = {};
levelInfo[levelArr[index]]["0"] = element;
}

const gui = new dat.GUI({
    load: {
        "preset": "level1", // 默认展示kkkks选项
        "closed": false,
        "remembered": levelInfo,
    }
});

But this is not easy to discover.
