引导按钮下拉式内部响应表不可见,因为滚动

我有一个问题与下拉按钮内的表时,响应和滚动活动,因为下拉是不可见的,因为 overflow: auto;属性。如何修复,以显示按钮下拉选项时,这是折叠?我可以使用一些 jQuery,但是在我遇到向左向右滚动的问题之后,所以我决定找到另一个解决方案。 为了更好地理解,我附上了一张照片

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;
}
}

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: inherit but this will work if you don't have the 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.

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" );
})

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 2¢ 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) :)

Note: I wrap it in a function so my IDE can collapse function ;) but it's not mandatory!

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%;
}

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;
}
}

More detail: https://github.com/twbs/bootstrap/issues/15374

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.

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: http://jsfiddle.net/s270Lyrd/

enter image description here

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');
}
});

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.

Simply Use This

.table-responsive {
overflow: inherit;
}

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

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>

Before: enter image description here

After dropdown is shown: enter image description here

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

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');
});

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

@media (min-width: 992px) {
.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

Define this properties. Good Luck!

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

In my case, this works fine:

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

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': ''});
});

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

pic-error

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" );
})

enter image description here

Try to do that way.

Try it once. after 1 hour of research on net I found Best Solution for this Problem.

Solution:- just add script

(function () {
// hold onto the drop down menu
var dropdownMenu;


// and when you show it, move it to the body
$(window).on('show.bs.dropdown', function (e) {


// grab the menu
dropdownMenu = $(e.target).find('.dropdown-menu');


// detach it and append it to the body
$('body').append(dropdownMenu.detach());


// grab the new offset position
var eOffset = $(e.target).offset();


// make sure to place it where it would normally go (this could be improved)
dropdownMenu.css({
'display': 'block',
'top': eOffset.top + $(e.target).outerHeight(),
'left': eOffset.left
});
});


// and when you hide it, reattach the drop down, and hide it normally
$(window).on('hide.bs.dropdown', function (e) {
$(e.target).append(dropdownMenu.detach());
dropdownMenu.hide();
});
})();

Solution

another solution is

.table-responsive{
min-height: 400px;
}

SIMPLE css only solution

Rather than modifying the parent table, Here I have a simple solution

The idea is to add z-index to the <td></td> that holds your dropdown. So that it will be on top of all other elements.

<td style="position: absolute; z-index: 10; width: 20%;"></td>

The solution for me was this:

.table-responsive {
min-height: 300px;
}


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

I've done some research and all the answers didn't solve it for me but they did sort-of point me in the right direction.

The boundary was already set to "window".

My <tbody> had a position: relative;. The dropdown-menu has a position: absolute;, but kept "relative" to the tbody, which caused the problems.

I changed the <tbody> to position: static;, which fixed my problem without any JavaScript, and the table is still responsive.


I'm using Bootstrap 4 by the way.

My simple JS solution without change global css rules.

Note: '.table-scrollable' you might need replace to '.table-responsive'

$('.table-scrollable').on('show.bs.dropdown', function (e) {
//get button position
offset = $(e.relatedTarget).offset()


//get button height
heigth = $(e.relatedTarget).outerHeight()


//append dropdown to body and perpare position.
$(e.relatedTarget).next('.dropdown-menu').addClass('dropdown-menu-in-table').appendTo("body").css({display:'block',top:offset.top+heigth, left: offset.left});
});


//move back dropdown menu to button and remove positon
$('body').on('hide.bs.dropdown', function (e) {
$(this).find('.dropdown-menu-in-table').removeClass('dropdown-menu-in-table').css({display:'',top:'', left: ''}).appendTo($(e.relatedTarget).parent());
});

Bootstrap 5 Solution

This is what worked best for me:

.table-responsive .dropdown,
.table-responsive .btn-group,
.table-responsive .btn-group-vertical {
position: static;
}

Using Bootstrap 5.2, with large tables that need to be responsive, this solution recently posted on Github (Nov 2022) - worked brilliantly for me:

I call the following javascript after rendering the drop-downs the first time (Blazor Server):

const dropdowns = document.querySelectorAll('.dropdown-toggle')
const dropdown = [...dropdowns].map((dropdownToggleEl) => new bootstrap.Dropdown(dropdownToggleEl, {
popperConfig(defaultBsPopperConfig) {
return { ...defaultBsPopperConfig, strategy: 'fixed' };
}
}));

Drop-downs can now expand outside of the table-responsive wrapper - without affecting the vertical size of the table or division - and works for both large and small screens.

in my case on boostrap vue with v-select inside inline-edit table i solved by ...

<style lang="scss" scoped>
...
...
.custom-yo-select >>> .vs__dropdown-menu {
max-height: 13em !important;
position: relative !important;
font-weight: 700 !important;
}
.custom-yo-select::v-deep .vs__dropdown-menu {
max-height: 13em !important;
position: relative !important;
font-weight: 700 !important;
}

here is the code

<v-select
v-if="
['select'].includes(data.field.input.type) &&
'columnKey' in data.field
"
v-model="
data.item[data.field.key.toString().split('.')[0]][
data.field.key.toString().split('.')[1]
]
"
class="custom-yo-select" // put the scss
:disabled="data.field.input.disabled"
:state="
data.field.columnKey === 'dm_master' &&
data.item[data.field.columnKey || data.field.key] === 0
? false

? true
: true
"
