{{clear}}
The templates {{tl|Componentbox begin}}, {{tl|Componentbox component}}, and {{tl|Componentbox end}} are used for listing the components of double and multiple stars and specifying their separation relative to a primary component.  The {{tl|Componentbox begin}} template is used first, followed by one use of {{tl|Componentbox component}} for each component, except the primary (assumed to be described elsewhere in the article); {{tl|Componentbox end}} is used to terminate the list.

An example is as follows:

<syntaxhighlight lang="wikitext">
{{Componentbox begin
|designation=[[Washington Double Star Catalog|WDS]]&nbsp;00004+7305
|footnote=<ref>Entry 00004+7305, 
[http://ad.usno.navy.mil/wds/wdsnewframe1.html The Washington Double Star Catalog], 
[[United States Naval Observatory]].  Accessed on line August 12, 2008.</ref>
}}
{{Componentbox component
|letter=B|primary=A
|appmag_v=13.0|epoch=2000|angdist=22.8|posang=282}}
{{Componentbox component
|letter=C|primary=A
|appmag_v=11.66|epoch=2000|angdist=44.4|posang=296}}
{{Componentbox end}}
</syntaxhighlight>

A fuller table, including right ascension, declination and a link to [[SIMBAD]] for each component may be displayed by adding the argument <kbd>expanded = yes</kbd> to {{tl|Componentbox begin}} and each occurrence of {{tl|Componentbox component}}:

<syntaxhighlight lang="wikitext">

[[United States Naval Observatory]].  Accessed on line August 12, 2008.</ref>
|expanded = yes
}}
{{Componentbox component
|letter=B|primary=A
|expanded = yes
|ra = {{RA|00|00|17.36}}
|dec = {{DEC|+73|05|00.9}}
|radec_footnote = <ref>{{SIMBAD link|**+HJ+3231B|CCDM J00003+7305B  -- Star in double system}},

{{Componentbox end}}
</syntaxhighlight>

When displayed together with a <kbd>References</kbd> section, these examples will appear as follows:

Detailed syntax for each template is as follows:

<syntaxhighlight lang="wikitext">

                  right ascension, declination and SIMBAD links -->

| footnote = <!-- Reference for designation and other table data -->
| equinox = <!-- Equinox of right ascension and declination, if present;
                 defaults to [[J2000.0]] -->
}}
