Title field character length Is it possible to limit the title field in an entry?  As with other fields I can adjust so that it only takes a certain amount of characters.
You can create a custom validation at the EVENT_BEFORE_SAVE event

Event::on(Entry::class,
    Entry::EVENT_BEFORE_SAVE,
    function(ModelEvent $event){
        /** @var Entry $entry */
        $entry = $event-&gt;sender;
        // you can check for the section and the type

        $model = DynamicModel::validateData(['title' =&gt; $entry-&gt;title], [
            [['title'], 'string', 'max' =&gt; 2, 'message'=&gt;'{attribute} should not be longer than 2 characters']
        ]);
        if($model-&gt;hasErrors()){
            $entry-&gt;addErrors($model-&gt;getErrors());
            $event-&gt;isValid = false;
        }
});


You can leave remove the message attribute if you don't want to use a custom error message, I just wanted to provide a full example how to validate data in Yii2. That way you can define whatever rule you want
