Using the Grid Editor view
The typical workflow for using the Grid Editor view is:
Add a template.
Drag a component from the Nav tree area onto the yellow Template Row.
Add a row
You can double-click directly on the Empty Query row to use the Component Grid Query Editor.
Note:Using a query (as opposed to dragging and dropping a component on the row) provides better point subscription service to points.
