Regarding this page:
Because I don’t have ‘Composer’, I have just added the mentioned line to the composer.json file. But this did not help.
After some tries, I have found the extensions.php file in the /vendor/yiisoft folder. I just extended this file with the yii2-jui folder.
'yiisoft/yii2-jui' => array ( 'name' => 'yiisoft/yii2-jui', 'version' => '18.104.22.168-beta', 'alias' => array ( '@yii/jui' => $vendorDir . '/yiisoft/yii2-jui', ), ),
Then the next problem… The example code mentioned here did not work, because it must be \yii\jui\Accordion in this case:
And another problem of the manual is that nowhere is mentioned that I first have to get this extension from for example github.com/yiisoft/yii2/tree/master/extensions
After all these steps it worked fine. At least I can see the accordion
Was the way how I did it totally wrong and therefore the reason, why it did not work easily?
Or was there a big misunderstanding regarding the documentation?
If not, it would be good, if the documentation could be updated accordingly.
