##### Overflow `auto` and `scroll`
Tooltip position attempts to automatically change when a parent container has `overflow: auto` or `overflow: scroll` like our `.table-responsive`, but still keeps the original placement's positioning. To resolve, set the `boundary` option to anything other than default value, `'scrollParent'`, such as `'window'`:
Tooltip position attempts to automatically change when a **parent container** has `overflow: auto` or `overflow: scroll` like our `.table-responsive`, but still keeps the original placement's positioning. To resolve this, set the [`boundary` option](https://popper.js.org/docs/v2/modifiers/flip/#boundary) (for the flip modifier using the `popperConfig` option) to any HTMLElement to override the default value, `'clippingParents'`, such as `document.body`:
```js
var exampleEl = document.getElementById('example')
var tooltip = new bootstrap.Tooltip(exampleEl, {
boundary: 'window'
boundary: document.body // or document.querySelector('#boundary')
})
```
