What it's doing in your video seems very logical. If any of the items at the next level are expandable, all items at that level move over so that their text and icons still line up vertically when the expandable items' disclosure triangles are drawn. Seems like the only other alternatives would be: 1. To *always* leave room for sub-item disclosure triangles, even when none are shown, so that there would be wasted blank space. 2. To let the icons/text of the sub-items not align vertically, depending on whether they were expandable or not. Each of those alternatives would have its own set of objections. If you must change the default behavior (which I wouldn't recommend doing just because you don't like it, since consistency with other apps is probably more beneficial to your users) you might be able to control it by overriding '-[NSOutlineView frameOfOutlineCellAtRow:]', or possibly even by using a different value for the "indentationMarkerFollowsCell" property. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
