Slicers

A slicer is a visual that filters other visuals on the page (or across pages when synced).

Users must narrow the dataset themselves and see the active selection at all times.

• •Specify default selection, single vs multi-select and whether search is needed.
• •Group slicers in one predictable region of the page.
• •Always provide a visible reset path (Clear all slicers button or bookmark).

• •Enable the search box in the slicer header menu for long lists.
• •Use Sync slicers to keep filter context across pages.
• •Consider Apply buttons on slow models so one refresh runs instead of many.

• •Default selection is correct on first load.
• •Reset returns to the default state, not to 'nothing selected'.

• •Information hierarchy and column order
• •Required fields and measures
• •Default state (sort, filters, selection)
• •Interaction intent and what it should affect
• •Responsive priority and what may be dropped
• •Accessibility expectations and focus order
• •Empty, loading and error states

• •Dataset fields, measures and relationships
• •Visual configuration in the format pane
• •Filters, sort order and interaction wiring
• •Drill-through / drill-down configuration
• •Conditional formatting rules
• •Row-level security and permissions
• •Query performance optimisation

• •Data correctness against the source
• •Correct default state on first load
• •Sorting and filtering behaviour
• •Drill and selection behaviour
• •Permissions and row-level security
• •Empty states and responsive layout
• •Performance and export behaviour
