GetNavChain

string
CMain::GetNavChain(
 mixed path = false,
 int start_from = 0, 
 mixed template_path = false
)

The method GetNavChain returns the HTML code of the navigation chain.

If you do not want some page to display the navigation chain, simply initialise the page property NOT_SHOW_NAV_CHAIN with "Y":

$APPLICATION->SetPageProperty("NOT_SHOW_NAV_CHAIN", "Y");

The method GetNavChain supports this property and respects its value.

Parameter	Description
path	Path for which the navigation chain is to be built. In case of multiple sites, if the DOCUMENT_ROOT of the site is different, pass an array in the following format: array("Site ID", "Path") Optional. False by default, which means the current site.
start_from	Ordinal of item from which to build the chain. Optional; zero by default.
template_path	Path to the navigation chain template. Optional. The default value is false, which implies searching for the navigation chain template using the algorithm described in the Navigation chain section.
