Rule-based styling – disabling the "else" option

[geguill]

Hello,
I have just tested rule-based styling for a vector layer (polygons), for example: ["==" , ["get", "CODE_INSEE"], "24"]
I would like any polygons that do not meet this rule to be invisible (without simply adjusting the outline transparency).
Essentially, I would like to know if it is possible to disable the "else" option.
Thanks in advance.

Thanks for the suggestion, @geguill! This is now implemented in #1313.

Once it lands, the Else (all other features) row in the rule-based renderer always shows an enable checkbox. Unchecking it hides every feature that matches no rule — fill, outline, and labels all disappear (no transparency tweaks needed), and hidden features no longer respond to identify clicks. Re-checking restores them. This matches QGIS behavior, where features matching no rule are simply not drawn when there is no ELSE rule.

For your example: keep your rule ["==", ["get", "CODE_INSEE"], "24"] and just uncheck the Else row — all other polygons become invisible.

Bonus: importing a QGIS QML (or SLD) whose rule tree has no ELSE rule now also hides unmatched features, matching what QGIS renders.
