[ Running Mathematica 9.0.1.0 under Ms Win XP Ver 5.1.2600 ]
Here I group toghter ;-) some relate questions about cell grouping, because I presume that they all pertain to the same cell options (or strictly siblings), but I can't figure out what they are.
I have just read SubTitle and SubSubTitle do not group by default and Making cells group but, may be, I misunderstood something.
Premise:
I have set (
Edit > Preferences > Show open/close icon for cell groups) 'On'I have set (
Format > Edit stylesheet I have set ShowGroupOpener) 'True' fortitle/subtitle/subsubtitle/section/subsection/subsusbsectionin the stylesheet we are talking about.
Now:
1a.
Subtitle cell still don't show the group opener
1b.
Subtitle cell still don't act as group operner/closer (I mean the opposite of Title or Section behaviour)
2.
Subsubtitle cell show the group opener only after the first one. Example
titlesubtitlesubsubtitle(no)subsubtitle(yes)subsubtitle(yes)
3.
I have created a new style undertitle and set it options ShowGroupOpener but
3a
GroupOpener is still missing
3b The same occur as described in 1b.
3c. After setting:
AllowGroupCLoseTrueCellGroupingRule{"TitleGrouping", 25}(I did because it is{"TitleGrouping", 20}forSubsubtitleand{"TitleGrouping", 30}forSection)AllowReverseGroupCLose'True'
3d Still the same occur as described in 1b.
Can you, please, point out the underlying problems and dispel a bit of the havoc I made ?
Thanks !!
