Hi TBM Heroes,
This question came up in class quite some time ago and I can't remember now who asked it. Anyway, it took me a while to find someone who knew the answer but I finally tracked it down. I tried to find the asker in my notes and email but was unsuccessful. Hopefully though you are following me and will see that I didn't give up on getting you an answer.
The question was related to an unusual menu option in one of the OOTB reports. This Tabbed table is in the OOTB Application Review report. About halfway down the page. Notice that rather than Size and Position, the right click menu shows an option to "Change Size" . A student in class was curious about where that option came from and why it doesn't exist in other places.
So it turns out that it's related to the group settings, The tab with the unusual menu item is nested inside a larger grouping component and that grouping component is set to use dynamic layout. When you have nested components inside a group that used dynamic layout, you won't get the option to specify the position of the item in the group, so it changes the menu to only offer a sizing option.
If you drag the tab component outside the group (not the easiest task since there are a lot of layers in this report) you can see that once it's outside the group the tab component once again has the Size and Position option. It's no longer controlled by the rules of the group.
Michelle McGuire - was it you who asked me about this?
