You can select both drawing objects and geospatial features at the same time. Use the drop-down list at the top of the Properties palette to switch between viewing the properties of all selected entities, viewing feature properties only, or viewing the properties for drawing objects by geometry type.
You can view the properties for up to 2000 features. If you select more features than that, all of them will be selected in your map and in Data Table. However, only the first 2000 features selected will be shown in the Properties palette.
When you select features on multiple layers, the drop-down list at the top of the Properties palette indicates how many checked-out features are selected. (If the features you selected are not checked out, the list shows only a single selection for each layer.)
The General properties indicate whether the Feature Class shown is for one or more layers, and whether the Feature ID is for one or more features. For multiple layers or features, these fields contain the text “VARIES.”
Properties for all selected layers are shown. You can change the Filter By Layer entry to see the properties for a single selected layer, or to switch between selected layers. For example, if you selected features that are stored on four different layers, select one of those layers to see its properties only. However, any features that were selected on the other layers remain selected.
To set the value for a property to “NULL,” click in the value field and select <NULL> from the drop-down list in that field. If <NULL> does not appear in the list, the property cannot have a null value.
