Adding content template, drop down menu. - Joomla! Forum - community, help and support

hi! provide content template editors.

for example, in each new content writing, must first fill in country name drop down menu, or there must static text each new page. publish it.

let's he's japan. , want write article. selects country "japan" drop down menu in new content page, , write article, , on top of every article static text saying "an article external source." output should be:

title of article
country: japan
an article external source.

content... bla bla bla...


so when editor adds new content, doesn't have type same thing on again, such text "an article external source". automatically inserted content. needs scroll down little bit more start putting in text.

any third party extension this? thank you!
