I have setup a quick jsFiddle to demonstrate the problem.
When using either a tooltip or a popover from Bootstrap on an option element of a select list, the popover or tooltip doesn't show next to the item, but rather in the extreme upper left of the page.
The HTML I am using is:
<select size="5" id="testList">
<option value="1" rel="popover" data-original-title="This is item 1." data-content="Lots of stuff to say" style="color: red; ">Item 1</option>
<option value="2" rel="popover" data-original-title="This is item 2." data-content="Lots of stuff to say" style="color: green; ">Item 2</option>
<option value="3" rel="popover" data-original-title="This is item 3." data-content="Lots of stuff to say" style="">Item 3</option>
<option value="4" rel="popover" data-original-title="Blah" data-content="Lots of stuff to say" style="color: orange; ">Item 4</option>
</select>
The javascript call is simple:
$(function () {
$('#testList option[rel=popover]').popover({
placement: 'right',
trigger: 'hover'
});
});
What can I do to make it show up in the right place?
It is expected. TB tooltip / popover calculates their position based on the associated elements offsetWidth and offsetHeight. Option does not have such properties, never has, so a popover will always end up in something relative to the farmost body left/top.
However, you can place a popover for the select itself. Bind mouseover for the select, from that show a popover to the right populated with data attributes for the option being hovered.
HTML, cleaned for rel="popover" and "data-original-title"
<select size="4" id="testList">
<option value="1" data-title="This is item 1." data-content="Lots of stuff to say 1" style="color:red;">Item 1</option>
<option value="2" data-title="This is item 2." data-content="Lots of stuff to say 2" style="color:green;">Item 2</option>
<option value="3" data-title="This is item 3." data-content="Lots of stuff to say 3" style="">Item 3</option>
<option value="4" data-title="Blah" data-content="Lots of stuff to say 4" style="color:orange;">Item 4</option>
</select>
bind mouseover, collect option data-attribues, show popover
$("#testList").on('mouseover', function(e) {
var $e = $(e.target);
if ($e.is('option')) {
$('#testList').popover('destroy');
$("#testList").popover({
trigger: 'manual',
placement: 'right',
title: $e.attr("data-title"),
content: $e.attr("data-content")
}).popover('show');
}
});
some cleanup so the popover disappears when we leave the select
$("#testList").on('mouseleave', function(e) {
$('#testList').popover('destroy');
});
doesnt think it can be done much better for an option list :) You could struggle with template, forcing the popover to more or less follow the vertical position for each option by its index.

Update - issues with IE and Chrome on windows.
I have seen some references to this answer, pointing out that it was not working in IE and Chrome on windows. It is due to the fact that on windows, <option> elements doesnt receive mouse events at all. Here is a "hack" of the above answer, making it "crossbrowser".
Sucesssfully tested with Chrome, FF, IE and Safari on Windows. Chrome, FF and Opera on Ubuntu. The idea is to target the correct <option> on mousemove (not mouseover) by calculating the index based on the mouseevents clientY / height of a option.
$("#testList").on('mousemove', function(e) {
if (!isWindows) {
var $e = $(e.target);
} else {
var newIndex = Math.floor(e.clientY/optionHeight);
if (newIndex === index) return;
index = newIndex;
$e = $(this).find('option:eq('+index+')');
}
if ($e.is('option')) {
$('#testList').popover('destroy');
$("#testList").popover({
trigger: 'manual',
placement: 'right',
title: $e.attr("data-title"),
content: $e.attr("data-content")
}).popover('show');
}
});
