sidebar-toggle adminlte not work in yii2 - yii2

Question

How can I fix my left side navigation. I am using AdminLTE 2.0in yii2 framework.
The problem is, the toggle side-bar not work after i do composer update yesterday (9.00 am Malaysia time).
I suspect the error must happen from javascript.
But could not find any.
Therefore, i give you my code to discuss here.
Thank You

Answer 1

Try to replace
data-toggle="offcanvas"
with
data-toggle="push-menu"

Answer 2

try to change composer.json
"dmstr/yii2-adminlte-asset": "2.*"
to
"dmstr/yii2-adminlte-asset": "2.4.4"
and then run "composer update"
this will solve menu toggle and menu tree view problems.

Answer 3

If you are on Admin-LTE 2.4.x,
Add data-widget="tree" to the sidebar menu. Specifically, it should look like this:
<ul class="sidebar-menu" data-widget="tree">
and
If your Sidebar Toggle is not working, do:
Change
data-toggle="offcanvas" to data-toggle="push-menu"

Answer 4

$(document).on('click', '[data-toggle="push-menu"]', function () {
if (!$('body').hasClass("sidebar-collapse") && $('body').hasClass("sidebar-open")) {
$('body').removeClass("sidebar-open");
$('body').addClass("sidebar-collapse");
$('body').addClass("sidebar-mini");
//console.log('menu kapa');
} else if($('body').hasClass("sidebar-collapse")) {
$('body').removeClass("sidebar-collapse");
$('body').addClass("sidebar-open");
//console.log('menu ac');
} else {
$('body').addClass("sidebar-collapse");
$('body').addClass("sidebar-open");
}
});

Answer 5

jQuery
$('[data-widget="pushmenu"]').on('click', function (){
$('[data-widget="pushmenu"]').PushMenu("toggle");
});
