Dear community,
Modal popup windows are a very frequently asked UI element Appian does not provide OOTB.
The purpose of a popup is to make any UI element fade into the background and provide an isolated area to require a specific input from the user. In Appian, we cannot implement this visual style directly, but we can achieve a very similar behavior. Instead, we hide all UI elements and display a single centered card layout. This card contains all the necessary elements. When a user clicks a button, the popup is closed, and the rest of the UI becomes visible again.
Read my blog post for more details.
