Changing the width of Bootstrap popover

Question

I am designing a page using Bootstrap 3. I am trying to use a popover with placement: right on an input element. The new Bootstrap ensures that if you use

Answer 1

For a typescript component:

@Component({
    selector: "your-component",
    templateUrl: "your-template.component.html",
    styles: [`
        :host >>> .popover {
          max-width: 100%;
        }
    `]
})

Answer 2

Try this:

var popover_size=($('.popover').css('width'));
var string=(popover_size).split('px');
alert("string"+string);
popover_size = ((parseInt(string[0])+350));
alert("ps"+popover_size);
$('.popover').css('width',parseInt(popover_size));

Answer 3

No final solution here :/ Just some thoughts how to "cleanly" solve this problem...

Updated version (jQuery 1.11 + Bootstrap 3.1.1 + class="col-xs-" instead of class="col-md-") of your original JSFiddle: http://jsfiddle.net/tkrotoff/N99h7/

Now the same JSFiddle with your proposed solution: http://jsfiddle.net/tkrotoff/N99h7/8/
It does not work: the popover is positioned relative to the <div class="col-*"> + imagine you have multiple inputs for the same <div class="col-*">...

So if we want to keep the popover on the inputs (semantically better):

• .popover { position: fixed; }: but then each time you scroll the page, the popover will not follow the scroll
• .popover { width: 100%; }: not that good since you still depend on the parent width (i.e <div class="col-*">
• .popover-content { white-space: nowrap; }: good only if the text inside the popover is shorter than max-width

See http://jsfiddle.net/tkrotoff/N99h7/11/

Maybe, using very recent browsers, the new CSS width values can solve the problem, I didn't try.

One tested solution for Bootstrap 4 beta:

.popover {
        min-width: 30em !important;
    }

Together with the jQuery statement:

$('[data-toggle="popover"]').popover({
      container: 'body',
      trigger: 'focus',
      html: true,
      placement: 'top'
    })

Side-note, data-container="body" or container: "body" in either HTML or as an option to the popover({}) object didn't really do the trick [maybe the do work but only together with the CSS statement];

Also, remember that Bootstrap 4 beta relies on popper.js for its popover and tooltip positioning (prior to that it was tether.js)

Answer 5

With the help of what @EML has described above regarding popover on modal windows and also the code shown by @2called-chaos, this is how I solved the problem.

I have a icon on the modal which when clicked should the popup

My HTML

<i title="" class="glyphicon glyphicon-info-sign" rel="popover" data-title="Several Lines" data-content="A - First line<br />B - Second line - Long line <br />C - Third Line - Long Long Long Line"></i>

My Script

    $('[rel=popover]').popover({
        placement: 'bottom',
        html: 'true',
        container: '#name-of-modal-window .modal-body'
    }).on("show.bs.popover", function () { $(this).data("bs.popover").tip().css("max-width", "600px"); });
