Preset filter control

You can add preset filters to your Looker Studio reports to let users quickly apply preset filter logic to a chart or report with the click of a button.

You can also create a  Reset filters button, which lets users quickly reset all filters. 

Requirements

To add a preset filter button to a report, you can use any existing boolean type dimension or create a calculated field that returns a boolean value. 

You must use a boolean type field because a filter button has only two states: selected or unselected.

Add preset filters to a report

1. Create or edit your report.
2. Select the Preset filter option from the Add a control drop-down menu. 
3. Drag and drop the button to position it in the desired location on your report.
4. Next, configure the filter using the options on the Setup tab in the Button properties panel. See the Configure preset filters section on this page for more information about configuring a preset filter.
5. Add a label to your filter button by clicking in the button and adding text to the text box on the report.

6. Customize your button appearance with the options in the Style tab in the Button properties panel. Read more about button style options in the Button style options section of the Adding buttons page.

Configure preset filters

Once you have added your preset filter button to your report, you can configure the following filter options in the Setup tab of the Button properties panel. 

Data source

View, edit, or replace the data source that is specified for the button.

Button action type

To create a preset filter, select the Filter option.

Control field

Select a boolean type dimension or create a calculated field that returns a boolean value.

To add a Control field, follow these steps: 

1. To access the field options for your data, select Add control field.
2. Select a field. You can search for a boolean field from your data, or you can select the ADD FIELD option to create a calculated field.
   
   For example, you can use the CONTAINS_TEXT function to create a calculated field with an expression that returns data for "United States" in a table that displays the population data for many countries:
   
   ​CONTAINS_TEXT(Country,"United States")

      This function lets users quickly filter a chart for "United States" data by clicking the filter button.

Default selection (true or false) 

When enabled, the Default selection (true or false) option automatically applies the filter to charts and reports without requiring user input. 

To disable the filter, a user has to click the button. 

This setting is optional. 

Button filter group

You can use the Button filter group drop-down to control how many filter options can be applied to a chart or report at one time. The number in the drop-down menu corresponds to a filter's group assignment. When one filter button is enabled in a group, the other filter buttons that are assigned to the same group will be disabled.

For example, if you have a table chart that displays population data for many different countries, you may want to configure several filter options for users to choose from.

You can create several filter buttons that let users filter by different countries, such as buttons for United States, Japan, or United Kingdom. You can use the Button filter group drop-down to assign the different country filter buttons to the same group. For example, assigning the United States, Japan,  and United Kingdom filter buttons to Button filter group drop-down option 1 ensures that only one country filter can be applied to the chart at once.  

You can specify up to five button filter groups per report page. 

This setting is optional.
