 This guide lists all the properties of the Data Grid 2 widget located inside the [Data Widgets](/appstore/modules/data-widgets/) module. Because data grids also contain columns and rows, properties for those [columns](#columns) and [rows](#rows) are also described below.

+Controls how loading states are displayed during data operations such as pagination, filtering, and refresh. Available options include spinner (rotating overlay) and skeleton (placeholder content). Loading indicators automatically appear during initial data load, pagination navigation, filter operations, sorting, and export operations. The system includes smart timing to prevent flickering on fast operations and provides appropriate timeout handling for slow operations.

+#### Filters Placeholder
+
+Container for filter widgets that operate on the entire grid. This placeholder provides a designated area for placing filter widgets (Text Filter, Date Filter, Number Filter, Drop-down Filter) that filter across all grid data rather than being limited to individual columns. Filter widgets placed here automatically link to the grid's datasource, and changes immediately affect the grid data. Still, widget should be configured to work properly. Multiple filters work together using AND logic by default.
