Thread:Extension talk:Vector/Is there a way to disable CollapsibleTabs?/reply

The Vector extension has full support for the toggling of individual features. This includes. By default, wikis installing this extension have  enabled for everyone without the option for users to disable it. This was probably done because it fixes problems where tabs would not fit on the screen (why would someone disable it ?).

But in case of Gadgets, you probably want to allow users to enable it. Simply set  to true to allow users to disable it (users using your gadget for example). Look here for the default configuration. Set the folllowing in LocalSettings.php (or, if for Wikipedia et al.), request so in :

$wgVectorFeatures['collapsibletabs']['user'] = true;
