Angular2 with Bootstrap Grid integration is a powerful combination for building

Struggling to implement bootstrap's grid layout system in Angular2 with a list of objects. Any tips or guidance would be greatly appreciated!

If I was using HandlebarsJS, I could achieve this layout with the following code:

{{#for elements}}
    {{#if index % 12 === 0}}
          <div class="row">
    {{/if}}
    <div class="col-md-2">
          {{element.name}}
    </div>
    {{#if index % 12 === 0}}
          </div>
    {{/if}}
{{/for}}

Desired output:

<div class="row">
    <div class="col-md-2">
        Bob
    </div>
    <div class="col-md-2">
        Joe
    </div>
    ...
</div>
<div class="row">
    <div class="col-md-2">
        Julie
    </div>
    <div class="col-md-2">
        Cheryl
    </div>
    ...
</div>

Delving into an age-old discussion, this time focusing on the latest version of Angular. If you're seeking innovative solutions for a similar query in Angular 1.x, do check out some insightful ideas here that can be tweaked to suit your current needs. Personally, I lean towards Duncan's approach, though preferences may vary. Below is a revamped rendition of his code tailored for Angular2 displayed elegantly on Codepen:

  <div class="row">
    <div *ngFor="let hero of heroes; let i = index">
      <div class="clearfix" *ngIf="i % 3 == 0"></div>
      <div class="col-md-4">{{hero.name}}</div>
    </div>
  </div>

Codepen Tip: The blue background signifies the row, while the red represents the col-md-* cell.

Observing the structure, you'll notice that all col-* elements are enclosed within a single row element, with a clearfix added every few iterations. In my opinion, this method offers a neat and sleek layout resembling something along the lines of Google Material Design Lite (MDL)-inspired grid setup rather than conforming strictly to Bootstrap norms.

While these solutions might not align precisely with your initial request, it's akin to comparing apples and oranges, each presenting its unique flavor.

Dealing with a similar challenge, we encountered the task of creating a list that could seamlessly switch between list and grid styles. One effective approach to implementing the grid style using bootstrap and angular 2 is by transforming the input array to suit the grid row/col structure.

To achieve this, you can generate a two-dimensional array of rows based on the desired number of columns. The example provided below showcases a fully dynamic version.

We trust that this solution will be beneficial to your project...

Component code:

export class Component implements OnChanges {

    @Input() items: any[] = [];
    @Input() gridCols: number = 4; // Define the number of columns in the grid
    private gridItems: any[][];
    private gridValidValues = [1, 2, 3, 4, 6, 12]; // Values divisible evenly for column count

    private initGrid() {
        this.gridCols = this.gridCols | 0; // Convert to integer
        this.gridCols = this.gridCols || 1; // Ensure at least one row

        if(!this.gridValidValues.find(value => this.gridCols === value)) {
            this.gridCols = 4; // Adjust invalid input to default column count
        }

        let addition = this.items.length % this.gridCols > 0 ? 1 : 0;
        let rows = ((this.items.length / this.gridCols) | 0) + addition;

        this.gridItems = [];

        let index = 0;
        for(var i = 0; i < rows; i++) {
            let row: any[] = [];

            for(var j = 0; j < this.gridCols && index < this.items.length; j++) {
                    row.push(this.items[index]);
                    index++;
            }

            this.gridItems.push(row);
        }
    }

    ngOnChanges(changes: SimpleChanges): void {
        let itemsChange: SimpleChange = changes["items"];

        if(itemsChange) {
            let previous: any[] = itemsChange.previousValue;
            let current: any[] = itemsChange.currentValue;

            if(previous.length != current.length) {
                this.initGrid();
            }
        }
    }
}

Template code:

<div class="row"
     template="ngFor let row of gridItems">
    <div bind-class="'col-md-' + (12 / gridCols)"
         template="ngFor let item of row">
        {{item.anyvalue}}
    </div>
</div>

                this.initGrid();
            }

    }
}
