5 columns per row in Bootstrap-4

问题

I have 15 records, I want to show all of it in a 5 columns per row. So I am using the auto column available in bootstrap 4 ".col", is there a way to limit column counts per row?

Note: I have to continuously loop the columns without breaking the row.

I want to achieve something like this

[ 1][ 2][ 3][ 4][ 5]
[ 6][ 7][ 8][ 9][10]
[11][12][13][14][15]

Here's my current code:

<div class="row">
    <!-- this will create 15 col -->
    <div class="col" ng-repeat="record in records">
        {{record.title}}
    </div>
</div>

But this results to:

[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]

For Bootstrap < 4.4 : Get rid of these Bootstrap columns and just use the magic of flexboxes.

Just add my .w-20 class to your CSS.

See it in action in my fiddle.

For Bootstrap >= 4.4 : Use the brand new row-cols-* classes

Add .row-cols-5 to your .row containing elements. No custom CSS needed.

See the 4.4 doc here : https://getbootstrap.com/docs/4.4/layout/grid/#row-columns

Now play with my fiddle and observe the same results in my fiddle with both techniques :

.w-20 {
  -webkit-box-flex: 0;
      -ms-flex: 0 0 20% !important;
          flex: 0 0 20% !important;
  max-width: 20%;
}

Seems you use AngularJS. If so, use an ng-reapt-start and ng-repeat-end and track the items of the list by $index. Use a break columns and show it only when ($index + 1) is 5, 10, or 15.

var app = angular.module('breakColumn', []);

app.controller('MainCtrl', function($scope) {
  $scope.list = [];
  for (let i = 1; i < 16; i++) {
    $scope.list.push(i)
  }
});

<div class="container" ng-app="breakColumn">
  <div class="row" ng-controller="MainCtrl">
    <div class="col bg-primary p-4 mb-3" ng-repeat-start="item in list track by $index" ng-init="itemIndex = $index">
      {{item}}
    </div>
    <!-- break column -->
    <div class="w-100" ng-repeat-end ng-if="(itemIndex +1) % 5 === 0"></div>
  </div>
</div>

If you're working with Bootstrap 4 scss files, then the easiest way is to use default mixin make-col(x,y). For example this code in a layout of 5 columns will create element that covers width of 2 columns. Basically it's 2/5 = 40%:

.my-col {
    @include make-col(2, 5);
}

This will result in following css:

.my-col {
    flex: 0 0 40%;
    max-width: 40%;
}
