Expandable Backgrid Cell

Backgrid.js expandable cell extension to create accordions on demand (when clicked in the target element)

For use, you just need to import and put it in your first column as a cell type. Then, you will need to define the funtion renderSubItems as a column attribute. This function will be responsible to generate the subitems that you will show when the line in the grid is explandabled.

Example

import ExpandableCell from './expandable-cell';

/* your other imports */

const collection = /* your Bacbone collection */;

const columns = [
  {
    cell: ExpandableCell,
    renderSubItems: function(collection, model) {
                const items = collection
                    .filter(items => items.get('ID').indexOf(model.get('ID')) === 0)
                    .map(item => {
                        return {
                            firstTD: '',
                            secondTD: item.get('myPropriety1'),
                            thirdTD: item.get('myPropriety2')
                        };
                    });
                return items;
            }
  },
  /* other Backgrid.js columns here */
];`

var grid = new Backgrid.Grid({
  columns: columns,
  collection: collection,
  className: 'table table-striped table-bordered table-hover'
});
