Bootstrap tool tip - setting different widths for different tooltips

(This Answer applies to BS 3.2) The only way I can think of achieving this is by overriding the default template for the tooltip. Then you use different selectors for large and regular tooltips like so;

DEMO

$('.tt_reg').tooltip();

$('.tt_large').tooltip({
    template: '<div class="tooltip" role="tooltip"><div class="tooltip-arrow"></div><div class="tooltip-inner large"></div></div>'
});

Note I've added the class large to the tooltip-inner element. You can then use css to adjust this size;

.large.tooltip-inner {
    width: 350px;
}

Give the container div a class:

<div class="large-tooltip">
    <i class="icon ion-help-circled" rel="tooltip" title="Hint"></i>
</div>

---

.large-tooltip .tooltip-inner {
    width: 250px;
}

In order to give different widths for tool-tips, rather than from adding different templates, it is possible to add different css classes for the container element and we can change the width of each element accordingly.
