Requirement: Remove “Show More” in the SharePoint task list new and edit forms!

To remove show more and display all fields of the task list, follow these steps:

1. Navigate to your Task list New form (such as: https://crescent.sharepoint.com/Lists/Tasks/NewForm.aspx) by clicking on “New Task”.
2. From the Site settings gear icon, click on “Edit Page” >> Click on the “Add a web part” link and then insert a “Script Editor” web part.
3. Click on the “Edit Snippet” link on the web part, insert this CSS in the script editor web part, save, and close the page.
