Multiple step not working properly

[nitinsonawane234]

Hello,
Here is my yii2 code for static 3 steps (without using model). It is showing 2 different next and previous buttons, as well as the content of 3rd step. when I click in next button (to goto on step2) it shows nothing.
Also the all links on demo page is not opening ie. https://yii2plugins.omaraslam.com/formwizard

use buttflattery\formwizard\FormWizard;

echo FormWizard::widget([
'steps' => [
[
'title' => 'My Shoots 1',
'description' => 'Add your shoots 1',
'formInfoText' => 'Fill all fields 1',
],
[
'title' => 'My Shoots 2',
'description' => 'Add your shoots 2',
'formInfoText' => 'Fill all fields 2',
],
[
'title' => 'My Shoots 3',
'description' => 'Add your shoots 3',
'formInfoText' => 'Fill all fields 3',
],
]
]);

Here is the output of step1:

Here is the output of step2:
