The following sidebar tabs give examples of grouped lists created by nesting.
!! Types Tab
!! [[Types Tab|$:/core/ui/MoreSideBar/Types]]
For the [[Types|$:/core/ui/MoreSideBar/Types]] tab, the outer list filter as shown below selects each discrete value found in the `type` field. The inner list filter selects all the (non-system) tiddlers with that type.
For the "Types Tab", the outer list filter as shown below selects each discrete value found in the `type` field. The inner list filter selects all the (non-system) tiddlers with that type.
<<tw-code "$:/core/ui/MoreSideBar/Types">>
!! Recent Tab
!! [[Recent Tab|$:/core/ui/SideBar/Recent]]
The list in the [[Recent|$:/core/ui/SideBar/Recent]] tab is generated using the <<.mlink timeline>> macro. Here, the outer list filter selects each discrete day found in the `modified` field, while the inner list filter selects all the tiddlers dated the same day in the `modified` field.
The list in the "Recent Tab" is generated using the <<.mlink timeline>> macro. Here, the outer list filter selects each discrete day found in the `modified` field, while the inner list filter selects all the tiddlers dated the same day in the `modified` field.

Note that if a tiddler does not contain field <<.place F>>, it is treated as if the value of the field were empty. Thus, a filter expression such as `[each[motovun]]` will return one tiddler that doesn't have a `motovun` field, as well as one tiddler with each distinct value of that field, if any. To obtain just the tiddlers that have a non-blank value for the `motovun` field one can use `[each[motovun]has[motovun]]`.
