Description

The CollapsibleColumns plugin allows collapsing of columns, covered by a header with the colspan property defined.

Clicking the "collapse/expand" button collapses (or expands) all "child" headers except the first one.

Setting the Options#collapsiblecolumns property to true will display a "collapse/expand" button in every header with a defined colspan property.

To limit this functionality to a smaller group of headers, define the collapsibleColumns property as an array of objects, as in the example below.

Example

const container = document.getElementById('example');
const hot = new Handsontable(container, {
  data: generateDataObj(),
  colHeaders: true,
  rowHeaders: true,
  nestedHeaders: true,
  // enable plugin
  collapsibleColumns: true,
});

// or
const hot = new Handsontable(container, {
  data: generateDataObj(),
  colHeaders: true,
  rowHeaders: true,
  nestedHeaders: true,
  // enable and configure which columns can be collapsed
  collapsibleColumns: [
    {row: -4, col: 1, collapsible: true},
    {row: -3, col: 5, collapsible: true}
  ],
});
