Expanded Filter Bar
Expanded Filter Bar
The filter dialog is the central component that shows all filters of the selected variant, allowing the user to add filters to the variant or remove them. Filters are arranged into their respective filter groups. The user can search for a specific filter by name in the search bar at the top.
The footer toolbar at the bottom of the dialog provides the following functions:
- Save: Saves your modified variant filter set (Save and Save As can be provided)
- Cancel: Closes the dialog and undoes all changes
- Restore: Restores the initial variant values (you can hide this button if it does not fit the app’s use case)
- Go: Executes the selected filter set
- Clear (optional): Clears all input fields/filters (this button should only be used if it fits the app’s use case)
The user can choose to hide filters on the expanded filter bar by deselecting the relevant checkbox next to the filter in the filter dialog (for example, if a filter is rarely edited, or unimportant).
Which filter control is used in the filter dialog or the expanded filter bar depends on the use case. Use the value help control if you want to offer an advanced function for selecting single or multiple items either inline (by entering text) or by means of a dialog. If there is a predefined list for single or multiple selection, use the combo box control. For temporal information you can use the date picker or date range selector.

Personalizing the Expanded Filter Bar
Default Variant Filters
- Mandatory / crucial to the use case
- Frequently used
- Vital for reducing the number of items in the list
Provide a meaningful default value for as many filters as possible. Meaningful default values depend on your use case.
A default value for date ranges, for example, should reflect the time frame the user would normally apply. App designers need to decide which time frame is appropriate.
Appropriate default values are particularly crucial for filter sets and list reports that operate on large data sets. In this case, consider making certain default filters mandatory to help the user avoid loading very large datasets unnecessarily.
Table Filtering and Table Searching
The filter bar can initially be collapsed or expanded, depending on the use case:
Initial State Collapsed
If the app has a default variant that is executed on loading, the table is prefilled, and the user seldom changes the filters, the app can start with a collapsed filter bar.
Initial State Expanded
If the app does not use a default variant and the user has to set a filter to obtain a first result set for the table, start with an expanded filter bar. Also, if a vast number of items are expected, include some mandatory filters. Since the user first has to enter values for these filters, start with an expanded filter bar. If you are in any doubt, start the app with an expanded filter bar.
Note: At least one filter must be defined to begin with. This filter is set within the basic group by app designers. If the use case allows, and depending on the size of the result set, provide a table that is initially filled.
Basic Search Field
Manual Update/Live Update
The filter bar is available in two separate modes: manual update mode and live update mode.
With manual update, the filter results are only updated when the user clicks or taps Go. A Go button is therefore mandatory in manual update mode. Pressing enter on the keyboard also triggers the filter.
With live update mode, the filter bar reacts instantly to every input change. The result table is updated every time the user changes a filter field or the search field. Therefore, a Go button is not necessary and is not shown if live update mode is used.
Additionally, the search is triggered with every letter that is entered. Starting with the first letter typed in, the table is updated with the results that match all set filters that include the search term.
Which One to Use
Use live update mode by default as it is more convenient for the user. If the user has to configure multiple filters to obtain a useful result set, or if the resulting traffic is expected to be excessively high, consider using manual update mode instead.
