title: Bootstrap tab is working but the tab content is not showing
body: <p>I am working on admin dashboard with html, css and javascripts. This is my first time working on it. I used bootstrap for the responsive layout and some bootstrap js (tabs, collaps). I also use chartjs for pie chart and line chart and sidr responsive menu. But the problem is with bootstrap tab and collaps function. They didn't work properly.When i click on the tab menu tabs are working but don't showing chart content in it. I spent lot of time to fix this. But i can't. I need your help.</p>
