javascript – Bootstrap button drop-down inside responsive table not visible because of scroll-ThrowExceptions

Exception or error:

I have a problem with drop-down buttons inside tables when are responsive and scroll active because the drop-down is not visible because of overflow: auto; property. How can I fix that in order to show drop-down option of button when this is collapsed? I can use some jQuery but after I have problems with scroll left-right so I decided to find another solution.
I have attached a photo to understand better.enter image description here

Here is a small js fiddle:

How to solve:

I solved myself this and I put the answer in scope to help other user that have same problem : We have an event in bootstrap and we can use that event to set overflow: inherited but this will work if you don’t have css property on your parent container.

$('.table-responsive').on('show.bs.dropdown', function () {
     $('.table-responsive').css( "overflow", "inherit" );
});

$('.table-responsive').on('hide.bs.dropdown', function () {
     $('.table-responsive').css( "overflow", "auto" );
})

and this is the fiddle

info: In this fiddle example works strange and I’m not sure why but in my project works just fine.

###

A CSS only solution is to allow the y-axis to overflow.

http://www.bootply.com/YvePJTDzI0

.table-responsive {
  overflow-y: visible !important;
}

EDIT

Another CSS only solution is to responsively apply the overflow based on viewport width:

@media (max-width: 767px) {
    .table-responsive .dropdown-menu {
        position: static !important;
    }
}
@media (min-width: 768px) {
    .table-responsive {
        overflow: inherit;
    }
}

For reference, it’s 2018 and I’m using BS4.1

Try adding data-boundary="viewport" to the button that toggles the dropdown (the one with the class dropdown-toggle). See https://getbootstrap.com/docs/4.1/components/dropdowns/#options

###

I’d took a different approach, I had detached the element from the parent and set it with position absolute by jQuery

Working JS fidle:

The JS solution I am using.

//fix menu overflow under the responsive table 
// hide menu on click... (This is a must because when we open a menu )
$(document).click(function (event) {
    //hide all our dropdowns
    $('.dropdown-menu[data-parent]').hide();

});
$(document).on('click', '.table-responsive [data-toggle="dropdown"]', function () {
    // if the button is inside a modal
    if ($('body').hasClass('modal-open')) {
        throw new Error("This solution is not working inside a responsive table inside a modal, you need to find out a way to calculate the modal Z-index and add it to the element")
        return true;
    }

    $buttonGroup = $(this).parent();
    if (!$buttonGroup.attr('data-attachedUl')) {
        var ts = +new Date;
        $ul = $(this).siblings('ul');
        $ul.attr('data-parent', ts);
        $buttonGroup.attr('data-attachedUl', ts);
        $(window).resize(function () {
            $ul.css('display', 'none').data('top');
        });
    } else {
        $ul = $('[data-parent=' + $buttonGroup.attr('data-attachedUl') + ']');
    }
    if (!$buttonGroup.hasClass('open')) {
        $ul.css('display', 'none');
        return;
    }
    dropDownFixPosition($(this).parent(), $ul);
    function dropDownFixPosition(button, dropdown) {
        var dropDownTop = button.offset().top + button.outerHeight();
        dropdown.css('top', dropDownTop + "px");
        dropdown.css('left', button.offset().left + "px");
        dropdown.css('position', "absolute");

        dropdown.css('width', dropdown.width());
        dropdown.css('heigt', dropdown.height());
        dropdown.css('display', 'block');
        dropdown.appendTo('body');
    }
});

###

This solution worked great for me :

@media (max-width: 767px) {
    .table-responsive .dropdown-menu {
        position: static !important;
    }
}
@media (min-width: 768px) {
    .table-responsive {
        overflow: visible;
    }
}

###

I have a solution using only CSS, just use position relative for dropdowns inside the table-responsive:

@media (max-width: 767px) {
  .table-responsive .dropdown-menu {
    position: relative; /* Sometimes needs !important */
  }
}

my 2ยข quick global fix:

// drop down in responsive table

(function () {
  $('.table-responsive').on('shown.bs.dropdown', function (e) {
    var $table = $(this),
        $menu = $(e.target).find('.dropdown-menu'),
        tableOffsetHeight = $table.offset().top + $table.height(),
        menuOffsetHeight = $menu.offset().top + $menu.outerHeight(true);

    if (menuOffsetHeight > tableOffsetHeight)
      $table.css("padding-bottom", menuOffsetHeight - tableOffsetHeight);
  });

  $('.table-responsive').on('hide.bs.dropdown', function () {
    $(this).css("padding-bottom", 0);
  })
})();

Explications:
When a dropdown-menu inside a ‘.table-responsive’ is shown, it calculate the height of the table and expand it (with padding) to match the height required to display the menu. The menu can be any size.

In my case, this is not the table that has the ‘.table-responsive’ class, it’s a wrapping div:

<div class="table-responsive" style="overflow:auto;">
    <table class="table table-hover table-bordered table-condensed server-sort">

So the $table var in the script is actually a div! (just to be clear… or not) ๐Ÿ™‚

Note: I wrap it in a function so my IDE can collapse function ๐Ÿ˜‰ but it’s not mandatory!

###

Define this properties. Good Luck!

data-toggle="dropdown" data-boundary="window"

###

Cleaned up @Wazime solution a little. Works great as a general solution.

$(document).on('shown.bs.dropdown', '.table-responsive', function (e) {
    // The .dropdown container
    var $container = $(e.target);

    // Find the actual .dropdown-menu
    var $dropdown = $container.find('.dropdown-menu');
    if ($dropdown.length) {
        // Save a reference to it, so we can find it after we've attached it to the body
        $container.data('dropdown-menu', $dropdown);
    } else {
        $dropdown = $container.data('dropdown-menu');
    }

    $dropdown.css('top', ($container.offset().top + $container.outerHeight()) + 'px');
    $dropdown.css('left', $container.offset().left + 'px');
    $dropdown.css('position', 'absolute');
    $dropdown.css('display', 'block');
    $dropdown.appendTo('body');
});

$(document).on('hide.bs.dropdown', '.table-responsive', function (e) {
    // Hide the dropdown menu bound to this button
    $(e.target).data('dropdown-menu').css('display', 'none');
});

The recommended and chosen solution, is not always the best solution. Unfortunately its the solution linkedin recently used and it creates multiple scrollbars on the page based on the situation.

My method was slightly different.

I contained the table-responsive div in another div. Then I applied height 100%, width:100%, display block and position absolute so the height and width is based on the page size, and set overflow to hidden.

Then on the table responsive div I added a min-height of 100%

<div class="table_container" 
    style="height: 100%; width: 100%; display: block;position: absolute;overflow: hidden;">
<div class="table-responsive" style="min-height:100%;">

As you can see in the working example below, no added scroll bars, no funny behavior, and practically as its using percentages – it should work regardless of screen size. I have not testing this for that however. If that fails for some reason, one can replace 100% with 100vh and 100vw respectively.

            </div>
</div>

Based on the accepted answer and the answer of @LeoCaseiro here is what I ended up using in my case :

@media (max-width: 767px) {
    .table-responsive{
        overflow-x: auto;
        overflow-y: auto;
    }
}
@media (min-width: 767px) {
    .table-responsive{
        overflow: inherit !important; /* Sometimes needs !important */
    }
}

on big screens the dropdown won’t be hidden behind the reponsive-table and in small screen it will be hidden but it’s ok because there is scrolls bar in mobile anyway.

Hope this help someone.

This has been fixed in Bootstrap v4.1 and above by adding data-boundary="viewport" (Bootstrap Dropdowns Docs)

But for earlier versions (v4.0 and below), I found this javascript snippet that works perfectly. It works for small tables and scrolling tables:

$('.table-responsive').on('shown.bs.dropdown', function (e) {
    var t = $(this),
        m = $(e.target).find('.dropdown-menu'),
        tb = t.offset().top + t.height(),
        mb = m.offset().top + m.outerHeight(true),
        d = 20; // Space for shadow + scrollbar.
    if (t[0].scrollWidth > t.innerWidth()) {
        if (mb + d > tb) {
            t.css('padding-bottom', ((mb + d) - tb));
        }
    }
    else {
        t.css('overflow', 'visible');
    }
}).on('hidden.bs.dropdown', function () {
    $(this).css({'padding-bottom': '', 'overflow': ''});
});

Burebistaruler response works ok for me on ios8 (iphone4s) but doen’t woks on android that before was working.
What i’ve donne that Works for me on ios8 (iphone4s) and andoir is:

$('.table-responsive').on('show.bs.dropdown', function () {
 $('.table-responsive').css( "min-height", "400px" );
});

$('.table-responsive').on('hide.bs.dropdown', function () {
     $('.table-responsive').css( "min-height", "none" );

This could be useful for someone else. I’m using DatatablesJS. I add 500px to the current height of the table. I do this because Datatables allow you to use 10, 20, etc pages in your table. So I need to calculate dinamically the table’s height.

When dropdown is shown, I add extra height.
When dropdown is hiden, I reset original table’s height.

$(document).ready(function() {
    $('.table-responsive .dropdown').on('shown.bs.dropdown', function () {
          console.log($('#table-responsive-cliente').height() + 500)
          $("#table-responsive-cliente").css("height",$('#table-responsive-cliente').height() + 500 );
    })

    $('.table-responsive .dropdown').on('hide.bs.dropdown', function () {
           $("#table-responsive-cliente").css("height","auto");
    })
})

And the HTML

<div class="table-responsive" id="table-responsive-cliente">
    <table class="table-striped table-hover">
     ....

     ....
    </table>
</div>

After dropdown is shown:

We solved this issue here at work by applying a .dropup class to the dropdown when the dropdown is close to the bottom of a table.enter image description here

This worked for me in Bootstrap 4 since it has different breakpoints than v3:

@media (min-width: 992px) {
    .table-responsive {
        overflow: inherit;
    }
}

###

As long as people still stuck in this issue and we are in 2020 already. I get a pure CSS solution by giving the drop down menu a flex display

this snippet works great with datatable-scroll-wrap class

.datatable-scroll-wrap .dropdown.dropup.open .dropdown-menu {
    display: flex;
}
.datatable-scroll-wrap .dropdown.dropup.open .dropdown-menu li a {
    display: flex;
}

Well, reading the top answer, i saw that it really dont works when you are seeing the scroll bar and the toggle button was on last column (in my case) or other column that is unseen

But, if you change ‘inherit’ for ‘hidden’ it will work.

$('.table-responsive').on('show.bs.dropdown', function () {
    $('.table-responsive').css( "overflow", "hidden" );
}).on('hide.bs.dropdown', function () {
    $('.table-responsive').css( "overflow", "auto" );
})

Try to do that way.

Inside bootstrap.css search the next code:

.fixed-table-body {
  overflow-x: auto;
  overflow-y: auto;
  height: 100%;
}

…and update with this:

.fixed-table-body {
  overflow-x: visible;
  overflow-y: visible;
  height: 100%;
}

###

Simply Use This

.table-responsive {
    overflow: inherit;
}

It works on Chrome, but not IE10 or Edge because inherit property is not supported

###

In my case, this works fine:

.table-responsive {
  overflow-y: visible !important;
}
