I have tested this item successfully on dbc02cb

Tested with success on last staging. Thanks!

Good spot that it should have a -select- string BUT I am not sure it is correct
Shouldnt it be - Select Content Map - that is the menu name

and the string Branches Only doesnt seem to make sense to me as it is actually All Branches or All Content Maps as its a parent item containing all the other content maps/branches.

If thats correct then the string Return to Branches should also probably be changed to Return to Content Maps

Branches only as well as Return to branches exist in core since the original porting of com_finder to Joomla.

See history (2011), where the terms branches and content maps are already present:
https://github.com/joomla/joomla-cms/blob/baa509338c8b92e41999fbc8d79ac755f9b6a761/administrator/language/en-GB/en-GB.com_finder.ini

We also have:
COM_FINDER_STATISTICS_STATS_DESCRIPTION="The indexed content on this site includes %s terms across %s links with %s attributes in %s branches."
COM_FINDER_MAPS_BRANCH_LINK="Select to show the children in this branch."
COM_FINDER_MAPS_MULTILANG="Note: Language filter system plugin has been enabled, so this branch will not be used."

We can obviously change whatever needed, but this patch is only correcting an error in #8140 where the Select should have been on top of dropdown and get rid of "Branches only" which never made any sense.

Looking further into this: there is a difference between Branches and Maps
A branch is a sort of category which contains maps (also called children)
I.e. when you display only one branch, its contents are maps, which you can publish/unpublish/delete if desired.

Therefore I would leave the terms alone and just merge this PR correcting #8140

String changed correctly

OK I guess any other change is out of scope so its a good test from me

2 good tests. RTC
