Exploring the positioning, placement, and orientation of Bootstrap popovers

Is there a way to prevent the bootstrap popover from moving away from the triggering element when the window is resized?

What CSS should be used to position the tip of the popover near the top corner instead of on the left?

Despite setting the placement as 'auto right', the popover is still appearing on the left side. Any insights on how to fix this?

$(function () {
  $('.js-tooltip-trigger').popover({
    html: true,
    trigger: 'focus',
    placement: 'auto right',
    content: function (e) {
        return $(this).parent(".form-group").find(".js-tooltip").html();
    }
  }).on('shown.bs.popover', function () {
       $('.popover').css('top',parseInt($('.popover').css('top')) + 22 + 'px')
     });
});

The HTML:

<div class="form-group">
<label for="ref">Reference</label>

<input type="text" class="form-control js-tooltip-trigger" id="ref" maxlength="50" >  

<div class="js-tooltip" style="display: none;">
    <p><strong>Your reference is optional.</strong></p>
    <p>Enter a code of your choice for reference purposes.</p>
</div>
</div>

Answer №1

This technique may not be everyone's favorite, but the concept involves creating an element that remains in a specific position to act as a reference for the popover. The popover is then appended to this designated element. In this scenario, I have utilized the existing container meant for tooltip HTML and dynamically generated container IDs to streamline the process.

Consider the following HTML structure:

<div class="form-group pos-relative">
    <label for="ref">Reference</label>
    <input type="text" class="form-control js-tooltip-trigger" id="ref" maxlength="50">
    <span class="js-tooltip" style="display: none;">
        <p><strong>Your reference is optional.</strong></p>
        <p>Enter a code of your choice for reference purposes.</p>
    </span>
</div>

The corresponding CSS would look like this:

.pos-relative{
  position:relative;
}
.js-tooltip{
   position:absolute; 
   top:0;
   right:0;
}

When it comes to JavaScript, the magic happens here:

$(function () {

  $('.js-tooltip-trigger').each(function(ind, ele){

    var $ele = $(ele),
        $ttSpan = $ele.next('.js-tooltip'),
        ttHtml = $ttSpan.html(),
        rndID = 'ttid'+ String(Math.random()).substr(2);

    // set the ID, strip the style, and empty the html--
    // we already have it stored in the var above
    $ttSpan.attr('id', rndID).removeAttr('style').html('');

    // create the popovers
    $ele.popover({
        html: true,
        trigger: 'focus',
        placement: 'right',
        container: '#'+rndID, 
        content: ttHtml
    });

  });

});
