Hide a Category from the Property Grid

This sample demonstrates how to handle the onShowingProperty event to hide all properties in the 'Logic' category and the 'Logic' category itself.

Currently, there is no single option to hide a category in the Properties grid for all survey elements (pages, panels, questions of different types). Actually, a category in the Properties grid hides automatically, if all its properties become hidden. So, to hide a category, you can iterate through all properties and hide those which belong to this category.

The definition of all question properties (together with the related categories/tabs) can be found in our sources, in the following file: questionEditorDefinition.ts

To hide the 'Logic' category, you can review the questionEditorDefinition.ts file and populate a stop-list array (propertyStopList in the sample code) with properties that contain 'tab: "logic"'. Then handle the Creator's onShowingProperty event and prevent the display of properties contained in the black list. As a result, the 'Logic' category hides automatically if it does not contain any property.
