Symbols

Big one dot

Big one dot "•" means "end of the branch". There are no further child items for that branch.

Small three dots

Small three dots "…" means "child item abbreviated". There is further child item for that branch. But it is abbreviated. Because already exceeded recursion limit. If you want show abbreviated items, increase recursion number setting.

Infinity symbol and Upwards arrow

Infinity symbol and Upwards arrow "∞ ↑" means infinite loop is detected. Same item is linked with at sign "@", asterisk "*", or sharp "#".

Other symbols

At sign "@", asterisk "*", and sharp "#" are used when same item appears twice or more times in different branches of the tree. Same items are abbreviated by these symbols except last occurrence.

Huge tree

Huge tree sometimes exceeds the limit of "expensive parser function count" (w:en:WP:EXPENSIVE). As of 2017, maximum expensive parser function count is 500. When accessing one Wikidata item page through Lua function (for example mw.wikibase.getEntity()), it raises expensive parser function count by one. So it is not possible to render huge tree which includes over 500 items. If the count reaches over 500, this template returns error Lua error: too many expensive function calls. And automatically categorized into Category:Pages with too many expensive parser function calls. In such case, try decreasing recursion number setting for shortening tree.

You can check the current expensive parser function count of each page by following manner.

Go to "Redaktoni" mode → "Parapamje" → Scroll down to around the middle of the preview page → Click and open the "Parser profiling data:" table → Check Expensive parser function count shown there, like 142/500

Example

{{Tree|property=40|items=Q1154861|recursion=50}}
