Description

The plugin allows filtering the table data either by the built-in component or with the API.

See the filtering demo for examples.

Example

const container = document.getElementById('example');
const hot = new Handsontable(container, {
  data: getData(),
  colHeaders: true,
  rowHeaders: true,
  dropdownMenu: true,
  filters: true
});

Options

filters

Source code (opens new window)

filters.filters : boolean

The filters option configures the Filters plugin.

You can set the filters option to one of the following:

Setting	Description
false	Disable the Filters plugin

Methods

addCondition

Source code (opens new window)

filters.addCondition(column, name, args, [operationId])

Adds condition to the conditions collection at specified column index.

Possible predefined conditions:

• begins_with - Begins with
• between - Between
• by_value - By value
• contains - Contains
• empty - Empty
• ends_with - Ends with
• eq - Equal
• gt - Greater than
• gte - Greater than or equal
• lt - Less than
• lte - Less than or equal
• none - None (no filter)
• not_between - Not between
• not_contains - Not contains
• not_empty - Not empty
• neq - Not equal.

Possible operations on collection of conditions:

• conjunction - Conjunction (opens new window) on conditions collection (by default), i.e. for such operation:
  c1 AND c2 AND c3 AND c4 ... AND cn === TRUE, where c1 ... cn are conditions.
• disjunction - Disjunction (opens new window) on conditions collection, i.e. for such operation:
  c1 OR c2 OR c3 OR c4 ... OR cn === TRUE, where c1, c2, c3, c4 ... cn are conditions.
• disjunctionWithExtraCondition - Disjunction on first n - 1* conditions from collection with an extra requirement computed from the last condition, i.e. for such operation:
  c1 OR c2 OR c3 OR c4 ... OR cn-1 AND cn === TRUE, where c1, c2, c3, c4 ... cn are conditions.

* when n is collection size; it's used i.e. for one operation introduced from UI (when choosing from filter's drop-down menu two conditions with OR operator between them, mixed with choosing values from the multiple choice select)

Note: Mind that you cannot mix different types of operations (for instance, if you use conjunction, use it consequently for a particular column).

Example

const container = document.getElementById('example');
const hot = new Handsontable(container, {
  data: getData(),
  filters: true
});

// access to filters plugin instance
const filtersPlugin = hot.getPlugin('filters');

// add filter "Greater than" 95 to column at index 1
filtersPlugin.addCondition(1, 'gt', [95]);
filtersPlugin.filter();

// add filter "By value" to column at index 1
// in this case all value's that don't match will be filtered.
filtersPlugin.addCondition(1, 'by_value', [['ing', 'ed', 'as', 'on']]);
filtersPlugin.filter();

// add filter "Begins with" with value "de" AND "Not contains" with value "ing"
filtersPlugin.addCondition(1, 'begins_with', ['de'], 'conjunction');
filtersPlugin.addCondition(1, 'not_contains', ['ing'], 'conjunction');
filtersPlugin.filter();

// add filter "Begins with" with value "de" OR "Not contains" with value "ing"
filtersPlugin.addCondition(1, 'begins_with', ['de'], 'disjunction');
filtersPlugin.addCondition(1, 'not_contains', ['ing'], 'disjunction');
filtersPlugin.filter();
