Combobox

The Combo Box Filter is an interactive component used in dashboards and reports to filter data on associated components. It provides a drop-down list of selectable items. Choosing one or more items dynamically changes the data displayed in linked visualizations or components.

The Combo Box is versatile and can support single, default, or multi-selection with checkboxes, making it suitable for a wide range of filtering needs.

Best Situations to Use Combo Box

Use a Combo Box Filter when you need to:

• Allow users to filter associated components dynamically.

• Select a specific item (e.g., a single region, department, or product).

• Enable multi-select filtering for broader analysis (e.g., multiple categories at once).

• Provide a searchable dropdown for datasets with many options.

Example use cases:

• Selecting a region to update all associated sales charts.

• Choosing a product line to drill into performance dashboards.

• Applying multi-category filters (e.g., “Electronics” + “Home Appliances”).
