JavaScript/jQuery FilterBuilder Options

Default Value: false

The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.

Use this property when you display the component on a platform whose guidelines include the active state change for UI components. See the following GitHub repository for an example of this type of platform: MUI.

allowHierarchicalFields

Specifies whether the UI component can display hierarchical data fields.

Type:

Array<FilterBuilder Custom Operation>

Default Value: false

customOperations[]

Configures custom filter operations.

Type:

Default Value: []

disabled

Specifies whether the UI component responds to user interaction.

Type:

Array<FilterBuilder Field>

Default Value: false

elementAttr

Specifies the global attributes to be attached to the UI component's container element.

Type: any

Default Value: {}
