How to fix some divs on top while scrolling using bootstrap? - html

Question

I am using bootstrap in Angular 2 project and I want to freeze couple of divs(with ids as filters and categories in the code) on top always, while user scrolls down the page.
This is the code that I have in jsfiddle here
Code Snippet:
<nav class="navbar navbar-default navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div id="navbar" class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li routerLinkActive="active"><a routerLink="/overview">Overview</a></li>
<li routerLinkActive="active"><a routerLink="/insights">Insights</a></li>
</ul>
</div>
<!--/.nav-collapse -->
</div>
</nav>
<div id="filters" class="container-fluid" style="margin-top: 60px" >
<div class="row">
<div class="col-md-2 col-sm-4">
<button>Filter 1</button>
</div>
<div class="col-md-2 col-sm-4">
<button>Filter 2</button>
</div>
</div>
</div>
<div id="categories" class="container-fluid" >
<div class="row">
<ul class="nav navbar-nav">
<li><a routerLink="#">Sub Category 1</a></li>
<li><a routerLink="#">Sub Category 2</a></li>
</ul>
</div>
<div class="row">
<div class="col-md-6 col-sm-12 col-xs-12">
<div style="background: blue; height: 800px;">
Trend Chart
</div>
</div>
<div class="col-md-6 col-sm-12 col-xs-12">
<div style="background: green; height: 800px;">
Bar Chart
</div>
</div>
</div>
</div>
I have tried using bootstrap's 'affix', but it is breaking the scroll and the margins of 'filters' and 'categories' divs, as can be seen here
Kindly let me know if I am missing anything else that needs to be added for affix to work.

Answer 1

To achieve your goal you need to use position: fixed and z-index: 1030 CSS with your div
Here's the jsfiddle
Use this CSS in your div
<div id="filters" class="container-fluid"
style="margin-top: 60px; position: fixed; z-index: 1030;">
<div class="row">
<div class="col-md-2 col-sm-4">
<button>Filter 1</button>
</div>
<div class="col-md-2 col-sm-4">
<button>Filter 2</button>
</div>
</div>
</div>

Answer 2

Use the style attribute "position:fixed" in both the div you want to be fixed.
Also set z-index value above 100. (this is to show the fixed div over all other div while scrolling).
Example:
<div id="filters" class="container-fluid" style="margin-top: 60px;position:fixed;z-index:999;" >
<div class="row">
<div class="col-md-2 col-sm-4">
<button>Filter 1</button>
</div>
<div class="col-md-2 col-sm-4">
<button>Filter 2</button>
</div>
</div>
</div>
<div id="categories" class="container-fluid" style="position:fixed;z-index:999;" >
<div class="row">
<ul class="nav navbar-nav">
<li><a routerLink="#">Sub Category 1</a></li>
<li><a routerLink="#">Sub Category 2</a></li>
</ul>
</div>
<div class="row">
<div class="col-md-6 col-sm-12 col-xs-12">
<div style="background: blue; height: 800px;">
Trend Chart
</div>
</div>
<div class="col-md-6 col-sm-12 col-xs-12">
<div style="background: green; height: 800px;">
Bar Chart
</div>
