== Parameters ==
Aliases (alternatives) for each parameter or value are given in square brackets.

=== Format (first unnamed parameter) ===
The first parameter is an alphabetic code specifying the output format. The first letter concerns the image, the second the separator, and the third the country name. The parameter is fully case-insensitive.

If any position in the parameter value is missing or has a character not corresponding to an option below, the options marked as default will be used; e.g. a first parameter equal to <code>i</code>, <code>i**</code> or <code>izz</code> will be read as <code>isc</code>.

Some additional options can be enabled by appending the following letters to the three-letter code in any order:
{| class="wikitable"
! Letter !! Description !! Example
|- id="a"
| <code>a</code> || <u>A</u>dds the country name (the "name" parameter, or if unset the second unnamed parameter) as <u>a</u>lt text and mouseover for the image.

|- id="e"
| <code>e</code> || Uses the name set in the country data template (rather than the first parameter) as display name, like in {{tl|flagcountry}} (i.e. <u>e</u>xpands abbreviated forms). || {{#invoke:DemoTemplate|flagg|unue|PAK}}

| <code>f</code> || If the prefixed/suffixed article name doesn't exist, <u>f</u>allback to linking to the non-prefixed/suffixed page.

| <code>l</code> || Adds the <u>l</u>ink name (as defined by the "image" parameter) as alt text and mouseover for the image. If [[#alt|{{para|alt}}]] is used for a custom alt/mouseover text, this does not need to be separately set. || {{#invoke:DemoTemplate|flagg|cxxl|PAK}}<br/>Compare with:<br/>{{#invoke:DemoTemplate|flagg|cxxa|PAK}}
|-
| <code>o</code> || <u>O</u>mits the image and spacing in case the image is an invisible placeholder, i.e., only include the spacing if a flag is displayed. Useful for inline/standalone usages or horizontal lists, where name alignment is not needed. || {{#invoke:DemoTemplate|flagg|unuo|Pakistan|image=}}<br/>Compare with:<br/>{{#invoke:DemoTemplate|flagg|unu|Pakistan|image=}}
|- id="r"
| <code>r</code> || Reverses the order of the elements, putting the image to the <u>r</u>ight of the name; cf. {{tl|flagright}}. Doesn't affect the order of letters in the format code. || {{#invoke:DemoTemplate|flagg|uncr|Pakistan}}

| <code>w</code> || Avoids <u>w</u>rapping by adding {{tag|span|params=class="nowrap"}} around the output. || {{#invoke:DemoTemplate|flagg|unuw|Pakistan}}
|- id="t"

=== Entity (second unnamed parameter) ===
The second parameter is the country or entity name. The template attempts to read the flag and link data from "Template:Country data ''country''"; if that does not exist, the same parameter will be used as default country link and no automatic image will be displayed. The parameter also defines the default displayed country name, if the [[#e|{{mono|e}}]] option above is not used.

=== Image parameters ===
;{{para|variant}} [third unnamed parameter]
:Specifies a variant flag image, as defined and documented in each entity's data template. For example, {{#invoke:DemoTemplate|flagg|ixx|Germany|naval}} uses the "naval" variant of [[Template:Country data Germany]].
;{{para|image}}
:Custom image name, with or without the "File:" namespace prefix. Can be used if the wanted image is not available as variant for the entity (you can alternatively request it be added at the respective data template's talk page), or if no data template exists. Set to "none" ["blank", empty string] to use an unlinked transparent image (functionally identical to the [[#x|{{mono|x}}]] format).
;{{para|size}} [{{para|sz}}]
:Sets the image size; default is 23&times;15 pixels (larger for [[:Category:Country data templates with distinct default size|some entities]]). You can use an explicit size in pixels (e.g. 30x20px; the "px" suffix is optional) or one of the relative sizes "xs" (half the default dimensions), "s", "m", "l" and "xl" (twice the default size).
;{{para|border}}
:By default, the flag icon includes a border, except if it is disabled in the entity's country data template. {{para|border}} can be set to "yes" ["y", "1"] to force a border when excluded by default, or "no" ["n", "0", empty string] to prevent one.
;{{anchor|align}}{{para|align}} [{{para|al}}]
:Set to "left" ["l"], "center" ["centre", "c", "middle", "m"] or "right" ["r"] to set the alignment of the image for the span box ([[#s|{{mono|s}}]]) and table cell ([[#t|{{mono|t}}]]) formats. For {{mono|t}}, the default is center; for {{mono|s}}, it is right-aligned if [[#r|{{mono|r}}]] is set, else left-aligned.
;{{para|width}} [{{para|w}}]
:Sets the width of the span box surrounding the image for the span box ([[#s|{{mono|s}}]]) format, in pixels, without the "px" suffix. The default is calculated by [[Module:Flaglist]] and depends on the image size.
;{{anchor|alt}}{{para|alt}}
:Sets alt text and mouseover text for the flag image, if it is for information rather than just decoration. If the wanted text is equal to the entity name, use the [[#a|{{mono|a}}]] option described above.
;{{para|ilink}}
:Overrides the link target of the image (only use if none of the image formats above allow linking to the desired page).
;{{para|noredlink|no}}
:Displays a red link to the missing country data template instead of a placeholder image. Defaults to "yes" (no red link displayed).
;{{para|missingcategory|''category name''}}
:Adds the page to ''category name'' if the image if the country data is missing.

=== Text and link parameters ===
;{{para|name}}
:Changes the displayed country name. Note that with the [[#f|{{mono|f}}]] format, this includes the prefix and/or suffix.
;{{para|clink}} [{{para|link}}]
:Overwrites the link to the country article; this is also used to construct the prefix/suffix link for the {{mono|f}}, {{mono|p}} and {{mono|b}} options.
;{{anchor|pref}}{{para|pref}}, {{para|suff}}, {{para|plink}}
:{{para|pref}} and {{para|suff}} set the prefix and suffix to use for the prefix/suffix links (format letters {{mono|f}}, {{mono|p}} and {{mono|b}}). The default, if neither is specified, is "Flag of" as prefix (cf. {{tl|flagof}}) and no suffix. {{para|plink}} can be used to override the combined link.
;{{para|the}}
:Set to "yes" ["y", "1"] to include the article "the" before the country name in the prefix/suffix links. Example: {{#invoke:DemoTemplate|flagg|usf|Philippines|the=1}}. Use {{para|pthe}} if the link needs "the" but the name doesn't, and {{para|nthe}} if the name needs it but the link doesn't.
;{{para|section}}
:Links to a section of the linked article without displaying the section name. If both a country link and a prefix/suffix link are used, use {{para|csection}} for a section of the country article, and {{para|psection}} for a section of the prefixed/suffixed article.
;{{para|altvar}} [{{para|avar}}], {{para|age}}
:Enables using one of a set of standard suffixes for linking to sports teams and militaries. The altvar and suffix data is loaded from [[Module:Flagg/Altvar data]]. The possible parameter values are the base names of the corresponding specialized templates; alias values from full sports names exist (see examples below and data page). For some entities this also changes the image to a variant specific to a sport or military branch; for example, {{#invoke:DemoTemplate|flagg|usp|Ireland|avar=ru}} uses the [[List of flags of Ireland#Sporting flags|IRFU flag]] to represent the Irish rugby union team. For youth teams in some sports (see the data page), the age limit must be additionally set using {{para|age}}.
;{{para|nalign}} [{{para|nal}}]
:Sets the alignment of the text in table cell format ({{mono|t}}). The default is left; the possible values are the same as for [[#align|{{para|align}}]].
;{{para|text}}
:Overrides the entire text; only use when necessary for any nonstandard formats. Alternatively, you can set the third letter of the format parameter to {{mono|x}} (no text) and add custom text outside the template.
;{{para|nodata|y}}
:Overrides attempts to use the corresponding {{tld|country data ...}} template, which is useful when the corresponding data template doesn't exist.
;{{para|pref2}}, {{para|suff2}}, {{para|plink2}}, {{para|psection2}}
: If the f extra is specified, and the prefix/suffixed article name being linked to doesn't exist, then use these parameters as an alternate prefix/suffix, and check if it exists as well. (If it still doesn't exist, then fall back to the non-prefixed/suffixed page as normal). This may be [[:mw:Help:Extension:ParserFunctions#ifexist_limits|expensive]], and the number of time it can be used on single page is limited.
