# HiddenRows

# Description

The HiddenRows plugin lets you hide specified rows.

"Hiding a row" means that the hidden row doesn't get rendered as a DOM element.

The HiddenRows plugin doesn't modify the source data, and doesn't participate in data transformation (the shape of the data returned by the getData*() methods stays intact).

You can set the following configuration options:

Option Required Type Default Description
rows No Array - Hides specified rows by default
indicators No Boolean false Shows UI indicators
copyPasteEnabled No Boolean true Sets up copy/paste behavior

Example

const container = document.getElementById('example');
const hot = new Handsontable(container, {
  data: getData(),
  hiddenRows: {
    copyPasteEnabled: true,
    indicators: true,
    rows: [1, 2, 5]
  }
});

// access the `HiddenRows` plugin's instance
const hiddenRowsPlugin = hot.getPlugin('hiddenRows');

// hide a single row
hiddenRowsPlugin.hideRow(1);

// hide multiple rows
hiddenRowsPlugin.hideRow(1, 2, 9);

// hide multiple rows as an array
hiddenRowsPlugin.hideRows([1, 2, 9]);

// unhide a single row
hiddenRowsPlugin.showRow(1);

// unhide multiple rows
hiddenRowsPlugin.showRow(1, 2, 9);

// unhide multiple rows as an array
hiddenRowsPlugin.showRows([1, 2, 9]);

// to see your changes, re-render your Handsontable instance
hot.render();
