Quick Filters
A quick filter is an interactive control card that sits on a worksheet or dashboard and lets viewers filter the data themselves — without editing the workbook. Dropdown lists, sliders, checkboxes, and search boxes all appear as quick filter card types in Tableau.
Showing a Filter as an Interactive Control
Any filter on the Filters shelf can be surfaced as an interactive control card. The card appears on the right side of the worksheet (or anywhere on a dashboard) and lets the viewer select, deselect, or slide through values without Tableau Desktop access. This turns a static chart into an explorable view.
Quick Filter Card Types
| Card Type | Field Type | Best Used When |
|---|---|---|
| Single Value (List) | Dimension | Viewer selects exactly one value at a time — radio button style |
| Single Value (Dropdown) | Dimension | Many values — dropdown saves space on the dashboard |
| Multiple Values (List) | Dimension | Viewer can check multiple values — checkbox style, default for most Dimensions |
| Multiple Values (Dropdown) | Dimension | Multi-select in a compact dropdown — good for long value lists |
| Multiple Values (Custom List) | Dimension | Viewer types values to search and add — best for high-cardinality fields like Customer Name |
| Wildcard Match | Dimension | Viewer types a text string — all matching values are included automatically |
| Range of Values | Measure or Date | Dual-handle slider — viewer drags min and max ends to define a range |
| Relative Date | Date | Last N days / weeks / months — always relative to today, ideal for operational dashboards |

Customising the Filter Card
Every filter card has a small dropdown arrow in its title bar that opens a customisation menu. The most useful options are:
Relative Date Filters
Relative date filters are the most useful quick filter for operational dashboards because they update automatically based on today's date. A filter set to Last 30 Days will always show the most recent 30 days regardless of when the dashboard is opened — no manual date adjustment required.
To create one: drag Order Date to the Filters shelf → select Relative Date in the filter dialog → choose Days and set the period to Last 30. Show the filter as a card and set the card type to Relative Date — viewers can then adjust the period themselves (Last 7 days, Last quarter, Year to Date) without editing the workbook.
Applying a Quick Filter Across Sheets
A filter card on a worksheet controls only that worksheet by default. To make it control multiple worksheets from a dashboard, right-click the filter pill → Apply to Worksheets → All Using This Data Source. When the filter card is then placed on a dashboard, changing its value updates every connected worksheet simultaneously — a single Region selector controlling a bar chart, a map, and a trend line all at once.
The card type choice matters more than most analysts realise. A Multiple Values List is the right default for a field with 4 to 8 values — viewers see all options at once and can check multiple. A Single Value Dropdown is correct for a field like Year where only one value should be active at a time. A Wildcard Match is the only sensible choice for high-cardinality fields like Customer Name or Product ID — showing 5,000 checkboxes in a list is unusable. The Only Relevant Values option is the single most important customisation on any multi-filter dashboard. Without it, a viewer can select a combination — say, Sub-Category = Tables and Region = South — and get an empty chart with no explanation. With Only Relevant Values active, the second filter automatically narrows to only the values that exist for the first filter's selection, preventing empty results entirely. Always enable it on dashboards with two or more interconnected filter cards.
Practice Questions
1. A Region filter is active on the Filters shelf but not visible to viewers. How do you surface it as an interactive control card on the worksheet?
2. A Customer Name field has 5,000 unique values. Which quick filter card type is most appropriate for this field?
3. A dashboard has two filter cards — Category and Sub-Category. Viewers keep selecting combinations that return empty charts. Which filter card setting prevents this?
Quiz
1. An operations dashboard needs to always show the last 30 days of data without anyone manually changing the date filter each day. Which filter type handles this automatically?
2. A Region filter card is currently showing as a Multiple Values List. You want to change it to a Single Value Dropdown. How do you do this?
3. A dashboard connects to a large live database and refreshes slowly every time a checkbox is clicked on a filter card. Which filter card option reduces the number of database queries triggered?
