<h1 id="popovers" class="page-header">Popovers <small>popover.js</small></h1>
|
||
|
||
<p>Add small overlays of content, like those on the iPad, to any element for housing secondary information.</p>
|
||
<p>Popovers whose both title and content are zero-length are never displayed.</p>
|
||
|
||
<div class="bs-callout bs-callout-danger" id="callout-popover-needs-tooltip">
|
||
<h4>Plugin dependency</h4>
|
||
<p>Popovers require the <a href="#tooltips">tooltip plugin</a> to be included in your version of Bootstrap.</p>
|
||
</div>
|
||
<div class="bs-callout bs-callout-danger" id="callout-popover-opt-in">
|
||
<h4>Opt-in functionality</h4>
|
||
<p>For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning <strong>you must initialize them yourself</strong>.</p>
|
||
<p>One way to initialize all popovers on a page would be to select them by their <code>data-toggle</code> attribute:</p>
|
||
{% highlight js %}
|
||
$(function () {
|
||
$('[data-toggle="popover"]').popover()
|
||
})
|
||
{% endhighlight %}
|
||
</div>
|
||
<div class="bs-callout bs-callout-warning" id="callout-popover-groups">
|
||
<h4>Popovers in button groups, input groups, and tables require special setting</h4>
|
||
<p>When using popovers on elements within a <code>.btn-group</code> or an <code>.input-group</code>, or on table-related elements (<code><td></code>, <code><th></code>, <code><tr></code>, <code><thead></code>, <code><tbody></code>, <code><tfoot></code>), you'll have to specify the option <code>container: 'body'</code> (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).</p>
|
||
</div>
|
||
<div class="bs-callout bs-callout-warning" id="callout-popover-hidden">
|
||
<h4>Don't try to show popovers on hidden elements</h4>
|
||
<p>Invoking <code>$(...).popover('show')</code> when the target element is <code>display: none;</code> will cause the popover to be incorrectly positioned.</p>
|
||
</div>
|
||
<div class="bs-callout bs-callout-info" id="callout-popover-disabled">
|
||
<h4>Popovers on disabled elements require wrapper elements</h4>
|
||
<p>To add a popover to a <code>disabled</code> or <code>.disabled</code> element, put the element inside of a <code><div></code> and apply the popover to that <code><div></code> instead.</p>
|
||
</div>
|
||
<div class="bs-callout bs-callout-info" id="callout-popover-multiline">
|
||
<h4>Multiple-line links</h4>
|
||
<p>Sometimes you want to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to center it horizontally and vertically. Add <code>white-space: nowrap;</code> to your anchors to avoid this.</p>
