The continent/region-topic templates allow quick creation of navigational template for groups of articles about a common topic in different countries of a continent/region. It uses :Template:Navbox to create the navigation box.  The lists of countries included in the "Continent topic" templates are broadly those found in the "Countries of" templates. Discussions on which countries to include are best conducted on the talk pages of these latter templates.  For example, Oceania generally includes Australia and the nations of the Pacific and islands in the Pacific Ocean that have closer ties to Asia or the Americas are usually grouped accordingly.   ব্যবহার    ১ম পরামিতি (উপসর্গ)  The most basic usage of template is with a single unnamed parameter in the format {{Continent/region topic |Topic [of/in]}}, replacing Continent/region with the name of a continent or region and Topic with the name of a topic followed by "of" or "in". For example, {{Africa topic |Geography of}} generates a navigation box titled "Geography of Africa" with a list of country names linked to articles such as Geography of Angola, etc. কোড  {{Africa topic |Geography of}} ফলাফল  The named parameter prefix can be used in place of the unnamed 1st parameter. কোড  {{Asia topic |prefix=Geography of}} ফলাফল   ২য় পরামিতি (অনুসর্গ)  The template accepts a second unnamed parameter for text to be placed after the country name. There is no space between the country name and the suffix, to allow for links to articles such as List of Spain-related topics.  This element is absent of : , , , ,  , ,   কোড  {{Europe topic |List of |-related topics}} ফলাফল  An underscore can be used to place a space between the country name and the text: কোড  {{North America topic |List of basic |_topics}} ফলাফল  Note that in the above example the links work but the underscore is displayed in the title.  This can be fixed by specifying a title (see next section) or by using the named parameter suffix which always places a space between the country name and text. কোড  {{South America topic |prefix=List of basic |suffix=topics}} ফলাফল   শিরোনাম পরিবর্তন  The title parameter is used to specify text which appears in the title bar at the top of the navigation box. This is optional because the use of prefix, suffix or both will automatically generate a title, as shown in the previous examples. This title is not automatically wiki-linked, so add brackets as needed.  The following shows a navigation box with links to articles such as Flag of Australia, but replaces the default title "Flag of Oceania" with the specified title "Flags of Oceania".  কোড  {{Oceania topic |Flag of |title=[[Flags of Oceania]]}} ফলাফল   শো মোডে টেমপ্লেট প্রদর্শিত হচ্ছে  These navigation boxes are set to autocollapse when there is more than one on a page. To force it into collapsed or expanded mode use the state parameter. If set to collapsed, the navbox will always start out in a collapsed state. If set to blank or anything other than autocollapse or collapsed, the navbox will always start out in an expanded state. কোড  {{Africa topic |prefix=Geography of |state=expand}} ফলাফল   Disabling dependencies and other territories  Not all dependencies or similar territories have their own articles on particular topics. To disable the inclusion of such territories in a template (that would otherwise appear as red links), include the parameter "countries_only=yes". কোড  {{Europe topic |prefix=Islam in |state=expanded |countries_only=yes}}: ফলাফল   নতুন টেমপ্লেট নির্মাণ  Although these templates can be used in an article, they can also be used to create a new template. The name parameter is mandatory when creating a new template, because it allows the "vde" links to work properly. The following example shows code that could be used to create Template:Flags of Europe.  {{Europe topic |name = Flags of Europe |state = {{{state|{{{1|}}}}}} |title = [[Flags of Europe]] |prefix = Flag of }}<noinclude> [[Category:Europe templates]] </noinclude>  The template can then be added to articles using {{Flags of Europe}} or {{Flags of Europe |state=expand}}.   টেমপ্লেট ব্যবহার করতে হলে    Before implementing these templates in a topic, check for red links. If there are several red links, consider whether a separate article in the topic for each country is warranted.  Some topics may use a different navigational scheme. In general, don't use this template if there are already navigational templates in several of the articles of a topic.  Examples of appropriate articles for these templates are {{Africa topic |Culture of}} or {{North America topic |List of airports in}}, both of which have a number of blue links, and where the majority of red links could have a reasonable article written about them.  Examples of inappropriate articles for these templates are {{North America topic |Maya in}}, where articles could only be written for a small number of nations and {{Oceania topic |Music of}}, where articles already have templates which use a different navigational scheme.  পুননির্দেশনা When there are a small number of links for which an article is not appropriate, consider making a redirect to the broader article in which the topic is included.  For example, Hinduism in Cambodia redirects to Hinduism in Southeast Asia and Geography of Christmas Island redirects to Christmas Island#Geography.   টীকা  ন্যাভিগেশানাল টেমপ্লেট সাধারণত একটি নিবন্ধের শেষে স্থাপিত হয়।
