Function

a!linkField( label, instructions, links, labelPosition, align, helpTooltip, showWhen, accessibilityText )

Displays one or more links of any link type, including document links, task links, record view links, external web page links, and dynamic links that update variables. Link types serve two main purposes: to navigate to objects, such as tasks and records, or to perform actions, such as downloading documents or starting processes.

Avoid using this component for offline mobile forms because links do not execute when tapped offline.

• Aggregate Data and Conditionally Display in a Chart or Grid (Reports, Charts, Query Data, Grids, Records): Aggregate data and conditionally display it in a pie chart or grid. In this pattern, we will calculate the total number of employees in each department and display it in a pie chart and a read-only grid. Then, we'll use a link field to conditionally display each component.

• Configure a Chart to Grid Toggle (Charts, Grids): Display a column chart with a toggle to display an alternate grid view of the data.
