Want to be able to drag over a grid row not before or after
I am using two grids where one is the dragable and the other the dropable. This works fine but I was wondering if there was a way to alter the way it looks. When I drag a row over my dropable row the dropable row is highlighted but there is also a line with arrows on either side implying the user can drop the row between, after or before the selected row which I don't allow. They can only drop on top of a row.
There isn't a specific config out of the box to do this. The case we were anticipating is that people were dragging records between two places and order mattered (not the case where users were associating a particular record with another record). This would be a good feature request for Ext JS.
Take a look at src/grid/ViewDropZone.js
You can do this by overriding the CSS rules .x-grid-drop-indicator-left and .x-grid-drop-indicator-right. Or you could override the indicatorHtml. If you needed to get more specific like highlighting a particular row would probably take more work in src/view/DropZone.js
