Tooltips & popovers in input groups require special setting

When using tooltips or popovers on elements within an .input-group, you'll have to specify the option container: 'body' to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip or popover is triggered).

Always add labels

Screen readers will have trouble with your forms if you don't include a label for every input. For these input groups, ensure that any additional label or functionality is conveyed to assistive technologies.

The exact technique to be used (<label> elements hidden using the .sr-only class, or use of the aria-label, aria-labelledby, aria-describedby, title or placeholder attribute) and what additional information will need to be conveyed will vary depending on the exact type of interface widget you're implementing. The examples in this section provide a few suggested, case-specific approaches.

## Basic example Place one add-on or button on either side of an input. You may also place one on both sides of an input. **We do not support multiple add-ons on a single side, nor multiple form-controls in a single input group.** {% example html %}

{% endexample %} ## Sizing Add the relative form sizing classes to the `.input-group` itself and contents within will automatically resize—no need for repeating the form control size classes on each element. {% example html %}

{% endexample %} ## Checkboxes and radio addons Place any checkbox or radio option within an input group's addon instead of text. {% example html %}
{% endexample %} ## Button addons Buttons in input groups are a bit different and require one extra level of nesting. Instead of `.input-group-addon`, you'll need to use `.input-group-btn` to wrap the buttons. This is required due to default browser styles that cannot be overridden. {% example html %}
