Breadcrumbs provide a pathway for users to navigate through your site.
Quite often you will see something like this which is called Breadcrumbs:
Breadcrumbs can be enabled or disabled via your site administrator area, and can usually placed in a site template module position, or for example at the top of an article or category.
The words "You are here:" can be chosen to be shown, or not shown, according to your administrator's preferences, as can the 'Home' text.
If you choose not to display the text: 'You are here' - your Breadcrumbs module will look like the next image . . .
And showing: 'You are here' text, but not showing: 'Home' text . . .
You can also choose to not show the 'You are here' text as well as not show the 'Home' text . . .
'Home' usually refers to your website desginated home-page.
The highlighted words can be clicked and doing so will take your visitor to that place on your website.Breadcrumbs can perhaps be seen as a trail that lets your website visitor know where he or she is in terms of the hierarchy of your site's navigation.
Breadcrumbs is all automatic - little configuration is required except setting up whether or not the words "You are here" is displayed or not.
In Joomla version 3.10.x Modules are created and managed via the administrator area menu 'Extensions' tab.
