In this tutorial video, we will learn how to run a Power Automate flow from a SharePoint list using the For a Selected Item trigger. We will use a flow template to trigger flow from SharePoint list button and add an on-demand flow approval process for the selected item. The flow template uses Input parameters that opens in a side panel in SharePoint. User can enter the approvers dynamically, set approval reminders and more. We will also leverage SharePoint list formatting to provide the user with a button to trigger the flow for the selected item in SharePoint list – You can use column formatting to create buttons that, when selected, run Flows on the corresponding list item. The Flow Launch Panel will be displayed after choosing the button and the Flow will just run.
