Custom attribute forms are a hidden treasure of QGIS 3.x. Users can add checkboxes, dropdown menus, radio buttons, and even conditional logic to the popup attribute form. In this webinar, participants will learn how to use the drag and drop designer to add various widgets, constraints, default values, and tabs to attribute forms. Further, we will show how forms can be saved as part of the default layer style and used by all users within an organization.
