Right now, if the Special:Drilldown page in Cargo sees a filter with 300 or more values, it just prints "Too many values; not displaying.", i.e. the message "cargo-drilldown-toomanyvalues". I think this was a bad UI decision on my part; instead, the page should print a simple text input, letting the user just enter a string for that filter.
Hints for anyone wanting to implement this:
- The resulting code should sort of look like CargoDrilldown::printComboBoxInput(), but less complex
- If you want to test it out, you don't need to have 300 values for some filter; you can just reduce that number to something low like 1 or 2.
