Not Auto Collapse When Creating Sub Item In Menu Of Bootstrap Adminlte Template

First of all I am a developer, not a designer. I am building Codeigniter project using Adminlte template. Now I face a problem. I will try to explain it using screenshots. Screens

Solution 1:

Try adding class "active" to the list item which needs to be stayed open.

<li class="active">

Solution 2:

I think that you have to add active class to li tag to work.
