Crosswalk Panel
^^^^^^^^^^^^^^^

The Crosswalk Panel is the base view for editing Crosswalks.

The panel has two main columns, one for each asset collection in the mapping.
If the asset-type on the left side has a primary key, then it will also have an extra column for that.

Like the Search Panel in other collections, users can filter-down the displayed assets by using the **Free Text** search, property-specific constraints added from the **Filters** drop-down, or the filters available in each column.

For each left-side asset, there are zero or more mapped right-side assets.
The mapping can be many-to-many, so viewers can swap the left/right collections via the **Toggle direction** button found in the panel's header.

To manually add a new mapping from a right-side asset to a left-side one, use the :ref:`MappingsPanel`.

First highlight the row you wish to add a mapping in the table panel.
This will cause the :ref:`MappingsPanel` to refresh for that particular row.
You can then enter the matches along with comments for that row.
Select each match from the dropdown and click the *add match* button.
You will see all of the mappings entered below the *add match* button.
If needed, you can delete a mapping from there.

To automatically generate potential matches, click the **Generate Mappings** button.
This opens the :ref:`ProblemsAndSuggestionsPanel`, which lists suggested asset mappings between the two collections.
EDG offers a default built-in generator of mappings.
If a different mapping algorithm is desired, TQ professional services can help with plugging additional algorithms for mapping crosswalks.
