What is a Breadcrumb ?

Breadcrumb refers to a navigation element mainly used on the web. It is used to indicate to the user at which hierarchical level the user is positioned.

As part of a business application created with 4D, Breadcrump will allow you to visualize all the steps of a process, to know the current step and to return to one of the previous steps of a processing or entry process.

To do this, the Breadcrumb is composed of sections that will allow you to navigate between different pages of a form or display specific subforms according to the hierarchy of the application's business logic.

The component AJUI_BreadCrumb is defined using an object variable representing an instance of AJUI_BreadCrumb. This variable contains a set of properties and formulas (member functions) to define the structure and content of the Breadcrumb and to generate it graphically in a 4D form.
