Repositioning
|
|
-----
|
|
|
|
Tethers will be automatically repositioned when the page is resized, and when any element containing the Tether is scrolled.
|
|
If the element moves for some other reason (e.g. with JavaScript), Tether won't know to reposition the element.
|
|
|
|
#### Manually Repositioning
|
|
|
|
The simplest way to reposition every Tether on the page is to call `Tether.position()`. It will efficiently reposition every
|
|
Tether in a single repaint, making it more efficient than manually repositioning many Tethers individually.
|
|
|
|
```javascript
|
|
Tether.position()
|
|
```
|
|
|
|
#### Repositioning a Single Tether
|
|
|
|
If you have many Tethers on screen, it may be more efficient to just reposition the tether that needs it. You can do this
|
|
by calling the `.position` method on the Tether instance:
|
|
|
|
```javascript
|
|
tether = new Tether({ ... })
|
|
|
|
// Later:
|
|
tether.position()
|
|
```
|
|
|
|
#### Tethering Hidden Elements
|
|
|
|
If you are creating a tether involving elements which are `display: none`, or not actually in the DOM,
|
|
your Tether may not be able to position itself properly. One way around this is to
|
|
ensure that a position call happens after all layouts have finished:
|
|
|
|
```javascript
|
|
myElement.style.display = 'block'
|
|
|
|
tether = new Tether({ ... })
|
|
|
|
setTimeout(function(){
|
|
tether.position();
|
|
})
|
|
```
|
|
|
|
In general however, you shouldn't have any trouble if both the element and the target are visible and in the DOM when you
|
|
create the Tether. If that is not the case, create the Tether disabled (option `enabled`: `false`), and enable it when
|
|
the elements are ready.
