Some [wikitr:/Plugins plugins] may simplify some steps, but provide less clarity about what you do: many tools, states or tags become "hidden" or even worse: simply inaccessible.

== Create a relation ==
1. Button [[JOSMImage(dialogs/add)]] in [wikitr:/Help/Dialog/RelationList Relations panel]
1. Tools specific to each [wikitr:/Help/Concepts/Object#Relations type of relation]

== Add/modify/remove tags of the relation ==
''All tags of the relations'' are entered based on {{{type=*}}} key ([wikitr:/Help/Concepts/Object#SimpleExplanation simple explanation]). You (or tools you're using) should specify {{{type=*}}} tag first, then [wikitr:/Introduction#Presets you can active presets] or add other details.

1. Using buttons in the [wikitr:/Help/Dialog/RelationEditor#TagsRelation "Tags" panel of Relation editor]
1. [wikitr:/Help/Dialog/SelectionList Select one or many relations], then add tags using regular tools that work on tags (there many of them: [wikitr:/Help#Tags Tags])

== Create a parent relation ==
Parent [wikitr:/Help/Concepts/Object#Relations relation] is a relation that consist of other relations as its children.

=== Load or create child relations ===
In this demo we simply pasted the relation [osmwww:relation/1152180 1152180] in active OSM data layer (make sure you have one first), other options covered at [wikitr:"/Help/Downloading data" Downloading data].

[[Image(create parent relation (route_master) - 1 load data or make sure you have all child relations in relations window.png,link=,50%)]]

=== Select at least one child relation in Relations list panel ===
In [wikitr:/Help/Dialog/RelationList Relations list panel]:

We are holding {{{Ctrl}}} to select multiple child relations at once in Relations list panel. But there [wikitr:/Help/Dialog/SelectionList#Selection many tools to select relations].

[[Image(create parent relation (route_master) - 2 optionally use ctrl to select multiple relations.png,link=,50%)]]

=== Selection list panel ===
In [wikitr:/Help/Dialog/SelectionList Selection list panel]:

* If you did nothing: nothing was sub-selected - it means everything is selected
* If only 2 items were selected in Selection list panel (using {{{Ctrl}}} but in this panel now), only 2 objects will be visible later on.

Nothing (everything) is selected:

[[Image(create parent relation (route_master) - 3.a refine subselection in selection window hold Ctrl and click at every child relation.png,link=,50%)]]

Only 2 objects are selected:

[[Image(create parent relation (route_master) - 3.b 2 route relations now selected in selection window.png,link=,50%)]]

=== Open Relation editor with selection ===
Click ''Plus button'' [[JOSMImage(dialogs/add)]] in ''Relations list panel'' to ''open relation editor with selected relations'':

[[Image(create parent relation (route_master) - 4 open relation editor with selected relations (Plus button in Relations window).png,link=,50%)]]

=== Relation editor ===
In [wikitr:/Help/Dialog/RelationEditor Relation editor]:

==== Add all of some members from selection to the left ====
Read hover captions or [wikitr:/Help/Dialog/RelationEditor Relation editor] page about what each button does.

[[Image(create parent relation (route_master) - 5 add all selected members to the left.png,link=,50%)]]

==== Add tags to parent relation ====
1. Use [wikitr:/Help/Dialog/RelationEditor#TagMember top part or relation editor] to add tags. ''Tags are different depending on what you want to detail, seek for help if you have questions about tags;'' \\
1. Press "OK"

[[Image(create parent relation (route_master) - 6 add tags to parent relation (top part or relation editor) and press ok.png,link=,50%)]]


== Remove or edit child relations ==
In public transport schema this is similar to edit/removing detour {{{route}}} relations from {{{route_master}}} relation.

1. [wikitr:/Help/Dialog/SelectionList#Selection Select a relation] that has other relations as it's members, open [wikitr:/Help/Dialog/RelationEditor Relation editor].
1. Select one or more members from the left (hold {{{Ctrl}}} to select multiple) and use according button, as described here: [wikitr:/Help/Dialog/RelationEditor#MembersList Bottom half left side members]

== Remove parent relations ==
Impossible ATM, but you can navigate to parent relation and remove respective child.

Select proper parent and press "edit" button in [wikitr:/Help/Dialog/RelationEditor#ParentRelations Parent Relations tab].

== Duplicate a relation ==
1. Button in [wikitr:/Help/Dialog/RelationList Relations list panel]
1. Button in [wikitr:/Help/Dialog/RelationEditor#Buttonsontop Relation editor]
1. TODO: other more specific tools

== Remove a relation ==
Please only remove relations when object in the world world is no longer exist.
Please [osmwiki:Good_practice#Keep_the_history keep history] whatever possible: select all members, remove them and add new members - this way you will continue editing of "old" relation.

1. Button in [wikitr:/Help/Dialog/RelationEditor#Buttonsontop Relation editor]
