The code below produces different results on test.wikipedia.org and test2.wikipedia.org. On test.wikipedia.com, collapsible text can only be expanded by selecting the "[Expand]" on the far right, whereas on test2.wikipedia.org, the text is expanded by clicking on "Check engine oil level."
==Process== Process examples to communicate issues and templates to coders and editors. Test. ====Drop down menu example==== * <span class="mw-customtoggle-EngineOil" style="color:#36c">Check engine oil level</span> <div class="mw-collapsible mw-collapsed" id="mw-customcollapsible-EngineOil"> :# Run vehicle to warm oil. :# Switch ignition OFF, wait at least 3 minutes to allow oil to flow back into pan. :# Remove dipstick and clean before reinserting back into tube. :# Remove dipstick again to read oil level. Ensure oil level is between MIN & MAX positions. :# Check oil level on instrument panel. Level will be slightly above the mid point of the oil gauge when engine is running hot. See Image :# Test line </div>
Further, on mediawiki 1.29.0, another problem exists that I was unable to test on test2.wikipedia.org, as it requires submission approval. On mediawiki 1.29.0, when a textual change is made in the "Edit" field, code is stripped. The following happens:
In the code below, if "Test" is removed, it changes the way collapsible text is viewed. Instead of clicking on the text to expand, a [Collapse]/[Expand] appears, as it did it my test on test.wikipedia.org.
