Bootstrap Tooltip可以工作，但是由于z-index隐藏了? [英] Bootstrap Tooltip working but hidden due to z-index?

问题描述

如果您将鼠标悬停在第一支铅笔上，您会看到工具提示即将出现，但是它被隐藏了.

If you hover over the first pencil, you can see the tooltip coming up but it's hidden.

我如何让所有工具提示都显示在其他所有内容之上?

How can I tell all tooltips to show up above everything else?

$('.nav-text').on('click', null, function () {
    alert('heyo');
});
$('.nav-text').tooltip({
    'placement': 'right',
        'title': 'heyo'
});

完整示例

$('.down').click(function() {
  var $move = $('.side-study-box ul');
  $move.css({
    top: '-=20px'
  })
})

$('.up').click(function() {
  var $move = $('.side-study-box ul');
  $move.css({
    top: '+=20px'
  })
})


$('.nav-text').on('click', null, function() {
  alert('heyo');
});
$('.nav-text').tooltip({
  'placement': 'right',
  'title': 'heyo'
});
