I am a newbie in Mediawiki.
I have a property Country with all countries as value.
And i have Project form having Counties field (Multi-select) [i.e ABC project is on 2 Countries (India and China)]
Now, for example
ABC => India, China
DEF => China, Japan
PQR => India, France
I want to build a map showing markers based on Countries [Property]
India marker should show "ABC, PQR"
China marker should show "ABC, DEF"
Japan marker should show "DEF"
France marker should show "PQR"
Please anybody help to build the query and show the map of Projects based on Countries
