Usage considerations

User, group, and user and group browser components comparison

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:

• User Browser
• Group Browser
• User and Group Browser

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.

To learn how to use these components, see the examples listed below:

• Example Interfaces for Group Browser Components
  • Navigation & the Initial Group
  • Selection for More Information
  • Selection for Picking

Saving, selecting, and displaying values

• If an initial group is not specified, only the label, tooltip, and instructions will be displayed.
• 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.
• Click a selected user to deselect the value. When a user is deselected, a null value is saved.

Using the pathValue and pathSaveInto parameters

• Because users can appear in multiple places in the browser at one time, a user only appears as selected if it is present in the pathValue array.
• When a user is selected, the variables in selectionSaveInto are updated after the variables in pathSaveInto. This means that if a variable is updated in both saves, it will be updated to the value assigned in the selectionSaveInto when a user is selected.
• When the component is read-only, the variables in selectionSaveInto are not updated when a user is clicked. However, if the selectionValue is set, a user can still be displayed as selected. pathSaveInto still updates as normal.
• A user can only be deselected if present in the pathValue.
• The first user or group in the pathValue must be a member of the initial group. Each subsequent user or group in the pathValue must be a member of the group that comes before it in the array. Otherwise, an error will occur.
