# Configuring Guided Navigation

The power user can set the following preferences for the Guided Navigation component.

The edit controls on the Guided Navigation component allow you to configure the layout so only facets relevant to the end user are exposed.

- Data source controls: Select from the available data sources in the drop-down list, and then click Update data source to bind your selection to the component.

- Configuration Options, including:

  - Enable type-ahead: Check to include the Type-ahead search box on dimensions with many dimension values.
    Important: Dimension search wildcarding must be enabled in the MDEX Engine in order for type-ahead to work in Discovery Framework components.
  - Maximum type-ahead suggestions: Set the maximum total number of type-ahead suggestions the MDEX Engine will offer. If fewer results are available, the number returned will be less than this maximum. Note that this control is only visible if Enable type-ahead is selected.
  - Enable automatic attribute updates in end user view: When enabled, the end user's view automatically reflects attribute changes in the MDEX Engine and in the Attribute Settings administrative component.
    Important: For data sources with large numbers of attributes, this feature may significantly reduce the speed and responsiveness of the end user's interface.
  - Maximum refinements to show in a single dimension: Set the maximum number of refinements per dimension to be displayed. This can help prevent your end users from being overwhelmed by an excessive number of results.
  - Target Page: Set the target page for any page transition. Page transitions allow a component on one page in your Discovery Framework application to pass data to a component on another page.
- Attribute list, including:

  - Search for an attribute by name.

  - Check which individual attributes or attribute sets to include. Attributes that are not selected are hidden from the end user's view.

  - Select attributes that will appear expanded by default in the end user's view. (The end user may choose to collapse expanded dimensions.)

  - Select attributes that can be used for negative as well as positive refinements. A negative refinement, when selected, is excluded from results.
