# Element.waitForElement

Wait for a matching element. Scoped to descendants.

```js
element.waitForElement(selector, optionsOrTimeout?)
```

## Arguments

| Argument | Type | Meaning |
| --- | --- | --- |
| `selector` | object \| string | Attribute filters; a string means {name: string}. See the UIHelper guide for selectors. |
| `optionsOrTimeout` | object \| number | Optional milliseconds, or {timeout:5000, interval:100, throwOnTimeout:true}. Interval is at least 10 ms. |

## Returns

Element; throws TimeoutError on timeout. With throwOnTimeout:false, returns null.

## Example

```js
const panel = UIHelper.waitForElement({id: "panel"}, 5000);
const field = panel.waitForElement({id: "search", visible: true, enabled: true}, 5000);
field.setText("Hello");
```

## Notes

The parent must still be valid. See the matching UIHelper method for options. Placeholder panel/child identifiers require inspection.
