Table Filters

When the user is building a table that needs filters, analyze the columns and design the filtering UX.

Step 1: Analyze Each Column

For each column in the table, determine the filter type:

Data Pattern	Filter Type	Example Columns
Free text, names, descriptions	Contains	Product Name, Notes, Customer
Fixed set of values (<20 options)	Checkboxes	Status, Category, Priority, Type
Numeric values	Range	Price, Quantity, Age, Score
Dates	Date Range	Created, Updated, Due Date
Boolean	Toggle	Active, Verified, Published

Step 2: Implement the Filter Layout

┌─────────────────────────────────────────────────────────┐
│ [Filter chips go here...] [🔍 Filter or search...]  [✕] │  ← Unified filter field
└─────────────────────────────────────────────────────────┘
                                          Sort by: [Dropdown ▾]

┌──────────────┬──────────────┬──────────────┬──────────────┐
│ Name       ▼ │ Status     ▼ │ Price      ▼ │ Created    ▼ │  ← Clickable headers with filter icon
├──────────────┼──────────────┼──────────────┼──────────────┤
│ ...          │ ...          │ ...          │ ...          │

Key layout rules:

Filter field spans table width, contains chips + search input + clear button
Sort dropdown next to filter field (not in headers)
Each header is clickable and opens its filter menu
Menu appears ABOVE field when filtering (inserts chip directly)

Step 3: Build Each Filter Component

Contains Filter (text)

┌─ Product Name ──────────── ✕ ─┐
│ ┌────────────────────────────┐│
│ │ Search...                  ││
│ └────────────────────────────┘│
└───────────────────────────────┘

Chip result:

Product Name: system

Checkbox Filter (categories)

┌─ Status ──────────────── ✕ ─┐
│ ☑ Active                     │
│ ☑ Pending                    │
│ ☐ Archived                   │
│ ☐ Deleted                    │
│            [Clear] [Apply]   │
└──────────────────────────────┘

Chip result:

Status: Active, Pending

Status: Active, +2

Range Filter (numeric)

┌─ Price ─────────────────── ✕ ─┐
│  Min         Max              │
│ ┌─────┐     ┌─────┐           │
│ │ 0   │  -  │ 100 │           │
│ └─────┘     └─────┘           │
│ ○───────────────●─────○       │  ← Optional slider
│              [Apply]          │
└───────────────────────────────┘

Chip result:

Price: $0 - $100

Date Range Filter

┌─ Created ─────────────────── ✕ ─┐
│  From           To              │
│ ┌──────────┐   ┌──────────┐     │
│ │ 01/01/25 │ - │ 12/31/25 │     │
│ └──────────┘   └──────────┘     │
│ [Today] [This week] [This month]│
│                [Apply]          │
└─────────────────────────────────┘

Chip result:

Created: Jan 1 - Dec 31, 2025

Chip Design Rules

Dark background, light text, rounded pill shape
X button on contrasting surface (clearly clickable)
Truncate after 2 values:
```
Status: Active, Pending, +3
```
Clicking chip reopens its filter menu

Empty State

When filters return no results:

     ┌─────────────┐
     │   (╯°□°)╯   │
     │   ︵ ┻━┻    │
     └─────────────┘
   No results found
   Try adjusting your filters

   [Clear all filters]

Quick Checklist

When implementing, verify:

Each column has appropriate filter type assigned
Filter field contains chips (not separate row above)
Sort is dropdown, not toggle icons in headers
Chip shows max 2 values, then +N
Clear all button at end of filter field
Empty state has clear action

HTML Class Reference

Use these classes for styling compatibility with

html-style

Element	Class	Purpose
Filter container	`.filter-bar`	Top-level filter row
Chip container	`.filter-chips`	Holds all active chips
Individual chip	`.chip`	Single filter chip
Chip remove	`.chip-remove`	X button on chip
Search input	`.filter-search`	Text search field
Clear all	`.filter-clear`	Clear all filters button
Sort control	`.sort-control`	Sort dropdown container
Filter menu	`.filter-menu`	Dropdown filter panel
Empty state	`.empty-state`	No results container

Data attributes:

```
