在ExtJS中拖动时删除反馈图标

Question

I have created a DataView in which items are internally draggable to rearrange, but the problem is that, while I can easily drag and re-arrange items within data view, while dragging, the overlay which is created of the item show "Red" feedback icon (which suggests that item cannot be dropped here), while I don't want any feedback icon to be shown (neither green or red), just an overlay of item is enough.

How to get rid of the feedback icon?

Short answer, you could just add these two CSS rules:

.x-dd-drag-ghost {
    padding-left: 5px;
}
.x-dd-drop-icon {
    display: none;
}

If you don't want to hide drag drop icon for the whole application, that's a bit more challenging... You have to add a custom css class to the Ext.dd.StatusProxy that will be created for your view. The StatusProxy is created in the constructor of Ext.dd.DragSource of which Ext.dd.DragZone is a subclass.

So, in the simplest case, if you're creating your drag zone yourself, you can add a class then:

var dragZone = Ext.create(...); // existing code
dragZone.proxy.addCls('no-icon');

Otherwise, you'll have to chase down the place where your drag zone/source is created...

Finally, here's the CSS for hiding only icons of proxies with the 'no-icon' class:

.x-dd-drag-proxy.no-icon .x-dd-drag-ghost {
    padding-left: 5px;
}
.x-dd-drag-proxy.no-icon .x-dd-drop-icon {
    display: none;
}
