User and Group Browser Component

Overview

The user and group browser components create Miller-columns-style browsers that allow users to select a user or group while browsing through a group membership tree.

The three group membership browsing components are:

Similar to the user and group picker fields, these three components appear the same but differ in what they allow to be selected. Depending on whether users, groups, or users and groups should be selected, choose the group browser, user browser, or user and group browser, respectively. If the interface is only for browsing, use the group browser, as it is the only browser that can be configured to show only groups and not users.

User and Group Browser

Function: a!usersAndGroupBrowserFieldColumns()

Displays group membership structure in columns. Users can navigate through the structure and select a single user or group.

Notes

  • If an Initial Group is not specified, only the Label, Tooltip, and Instructions will be displayed.
  • Because users and groups can appear in multiple places in the browser at one time, a user or group only appears as selected if it is present in the Navigation Path array.
  • When a user or group is selected, the variables in Save Selection To are updated after the variables in Save Navigation To. This means that if a variable is updated in both saves, it will be updated to the value assigned in the Save Selection To when a user or group is selected.
  • When the component is read-only, the variables in Save Selection To are not updated when a user or group is clicked. However, if the Selection Value is set, a user or group can still be displayed as selected. Save Navigation To still updates as normal.
  • Click a selected user or group to deselect the value. When a user or group is deselected, a null value is saved.
  • A user or group can only be deselected if present in the Navigation Path.
  • To make the selection required for submission or display validation messages based on the selection, pair the browser with a a picker or other component.
  • The first user or group in the Navigation Path must be a member of the Initial Group. Each subsequent user or group in the Navigation Path must be a member of the group that comes before it in the array. Otherwise, an error will occur.
