# Primary Operations

These are the three functions you use to manage menus.

### Typical flow

1. Optionally warm up assets with [`PreloadMenu`](/engine/reference/menus.js/primary-operations/preloadmenu.md).
2. Show the menu with [`LoadMenu`](/engine/reference/menus.js/primary-operations/loadmenu.md).
3. Remove it with [`UnloadMenu`](/engine/reference/menus.js/primary-operations/unloadmenu.md).

### Guidance for menu scripts

Write your menu JS to only touch `menuContainer`. That keeps cleanup simple on `UnloadMenu`.

Prefer scoped queries:

```javascript
const closeBtn = menuContainer.querySelector("[data-action='close']");
closeBtn?.addEventListener("click", () => UnloadMenu(menuId));
```

Use `extraData` for dynamic input. Avoid reaching into unrelated globals when possible.

{% hint style="info" %}
Avoid loading the same `menuId` twice. Duplicate `id="dMenu_<menuId>"` breaks `UnloadMenu`.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pvzm.net/engine/reference/menus.js/primary-operations.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
