Data Grid Filtering

Filtering

Filter the Data Grid with per-column filter dialogs (typed operators, AND/OR, set filter), a global search input, custom filter UIs and custom matching predicates.

The Data Grid filters on two levels. columnFilters: true adds a filter button with a dialog to every filterable column header; globalFilter: true adds a single search input above the grid that matches across every column (the same input as the toolbar’s search action). Both narrow the rows client-side (or feed your dataProvider in server-side mode). Opt a column out with filterable: false.

new coreui.DataGrid(element, {
  columns,
  items,
  columnFilters: true, // per-column filter buttons + dialog
  globalFilter: true,  // single cross-column search input
})

Filter menu

With columnFilters enabled every filterable column gets a filter button (funnel icon, configurable via filterIcon) in its header, opening a filter dialog. The dialog offers typed operators driven by column.filterTypetext (default), number and date get operator conditions (up to two, joined AND/OR), while select renders a faceted checkbox list of the column’s actual values. An active filter marks the button with a dot; the structured value travels inside the grid’s columnFilters state, so a dataProvider receives it verbatim.

Try it below: filter Salary with Between, Department with the set filter, or combine two conditions on Hired.

html
<div id="dataGridFilterMenu"></div>
js
const departments = ['Engineering', 'Design', 'Sales', 'Support']

const items = Array.from({ length: 200 }, (_, i) => ({
  name: `Employee ${String(i + 1).padStart(3, '0')}`,
  department: departments[i % departments.length],
  salary: 40_000 + ((i * 977) % 60_000),
  hired: new Date(2020, i % 60, (i % 27) + 1).toISOString().slice(0, 10)
}))

new coreui.DataGrid(document.getElementById('dataGridFilterMenu'), {
  columns: [
    { key: 'name', label: 'Name' },
    { key: 'department', label: 'Department', filterType: 'select' },
    { key: 'salary', label: 'Salary', filterType: 'number' },
    { key: 'hired', label: 'Hired', filterType: 'date' }
  ],
  items,
  columnFilters: true,
  columnMenu: true,
  pagination: { pageSize: 8 },
  sorting: false,
  virtualization: false
})

Custom column filters

Two per-column hooks customize filtering. filter renders your own UI in a dedicated filter row (shown only for columns that define it) — the same factory contract as slots, and the column hands you setFilterValue(), getFilterValue() and column.getFacetedUniqueValues() for building selects from the actual data. filterFn swaps the matching logic (default: case-insensitive contains, or the filter dialog’s structured value) for your own predicate (value, filterValue, item) => boolean — with a custom UI it receives exactly what that UI committed. Here Role pairs a faceted select with an exact-match predicate, while Score just declares filterType: 'number' and gets the built-in numeric dialog.

html
<div id="dataGridCustomFilters"></div>
js
const roles = ['admin', 'editor', 'viewer']

const items = Array.from({ length: 1000 }, (_, i) => ({
  id: i + 1,
  name: `User ${i + 1}`,
  email: `user${i + 1}@example.com`,
  role: roles[i % roles.length],
  score: (i * 37) % 1000
}))

new coreui.DataGrid(document.getElementById('dataGridCustomFilters'), {
  columnFilters: true,
  columns: [
    { key: 'name', label: 'Name' },
    { key: 'email', label: 'Email', style: { width: '30%' } },
    {
      key: 'role',
      label: 'Role',
      width: 160,
      // Exact match - the default contains would also match partial values.
      filterFn: (value, filterValue) => value === filterValue,
      filter({ column }) {
        const select = document.createElement('select')
        select.className = 'form-select form-select-sm'
        for (const value of ['', ...[...column.getFacetedUniqueValues().keys()].toSorted()]) {
          const option = document.createElement('option')
          option.value = value
          option.textContent = value === '' ? 'All' : value
          select.append(option)
        }

        select.addEventListener('change', () => column.setFilterValue(select.value || undefined))
        return { element: select }
      }
    },
    {
      key: 'score', label: 'Score', width: 140, filterType: 'number'
    }
  ],
  items,
  itemKey: item => String(item.id),
  pagination: { pageSize: 10 }
})

Custom filter API

Column keyTypeDescription
filterablebooleanSet false to remove the column’s filter button.
filter({ column, table, labels }) => { element, update?, dispose? }Custom filter UI rendered in the filter row instead of the filter button (requires columnFilters).
filterFn(value, filterValue, item) => booleanCustom predicate replacing the built-in matching; with the filter dialog it receives the structured value.

Every filter change emits filterChange.coreui.data-grid with { columnFilters, globalFilter }. A custom toolbar slot that hosts its own search box still needs globalFilter: true for the query to reach the grid.
