Tip: Interface patterns give you an opportunity to explore different interface designs. Be sure to check out How to Adapt a Pattern for Your Application.
The user list pattern retrieves all the users in a specified group and displays them in a single column. This page explains how you can use this pattern in your interface, and walks through the design structure in detail.
Each user's name and title appears next to their profile picture which uses the "avatar" style. Paging controls are provided at the bottom for browsing longer lists of users.
This pattern is also useful for:
The main components in this pattern are rich text headers, side by side layouts, and a rich text link. The image below displays how the pattern looks on a blank interface with callouts of the main components. You can examine the entire expression or jump down to the subsections below with referenced line numbers to see a detailed breakdown of the main components.
When you drag and drop the user list pattern onto your interface, 178-lines of expressions will be added to the section where you dragged it.

At the top of the pattern, local variables set up the following:
local!userListPagingInfo: Paging info for the list.

a!forEach() to loop over the list of usersThen, we use a!forEach() to loop over the list of users. Each user is represented by a single a!sideBysideLayout() containing two rich text display components. The first contains a!imageField() displaying the user's profile picture in the avatar style. The second contains two rich text items displaying the user's name and title.

Paging controls at the bottom are provided by a single richTextDisplayField with 5 richTextItems:
Tip: These paging controls are built with generic expressions that can handle any set of paged data.
