# allowNavigation method

void allowNavigation ([UriPolicy uriPolicy ])

Allows navigation elements- Form and Anchor tags, along with common attributes.

The UriPolicy can be used to restrict the locations the navigation elements are allowed to direct to. By default this will use the default UriPolicy.

## Implementation

    void allowNavigation([UriPolicy uriPolicy]) {
      if (uriPolicy == null) {
        uriPolicy = new UriPolicy();
      }
      add(new _SimpleNodeValidator.allowNavigation(uriPolicy));
    }
