Breadcrumbs builder inputs

Table 1. General inputs

Input Name	Description
Name	Required. Enter a unique name for this builder call. This name is displayed in the builder call list. It is also used in the identification of the LJO that is created. See Objects that the Breadcrumbs builder creates.
Prepare Page Method	Optional. This method performs any processing required to fetch the data associated with the key that is passed as input. See About navigating through model pages and About navigating through data.
Select Pages	If you check this input, the Pages Participating input appears for you to specify the pages. If this input is not checked, breadcrumbs are displayed if you call the select method in the LJO that the builder creates.
Pages Participating	This input appears only if the Select Pages input is checked. Select all pages in the model that participate in the breadcrumbs, that is, all pages which, when they are invoked, create a new breadcrumb in the list. For each model page, choose the selector that identifies that breadcrumb page to the breadcrumbs assistant. The selector can be an indirect value, which means that the same model page can appear several times in the breadcrumbs, under different values of the selector and can show different data. For example, in a catalog application, you can have a model page for showing a group of items to purchase. The key can represent which group to show.

Table 2. Breadcrumbs location inputs

Input Name	Description
Tag On Pages	Required. Specify a string that indicates the location on which pages display the breadcrumbs. Every page in the model with this tag shows breadcrumbs. See About navigating through data.
