How to add an icon to a search input in Bootstrap 4?

Bootstrap 4 - Search input with an icon

The question involves integrating an icon into a Bootstrap 4 search input. The issue arises as Bootstrap 4 does not support Glyphicons. Here's a detailed explanation of how to incorporate an icon into the search input using various techniques:

Input Group with Append

This technique uses an input-group with an append or a prepend for the icon. The icon is placed either before or after the input field.

<br><div>  <input class="form-control py-2" type="search" value="search">  <span><pre class="brush:php;toolbar:false"><button></button>

Input Group with Input Group Text

This technique utilizes an input-group with input-group-text for the icon. The input-group-text provides a placeholder for the icon without a gray background.

<br><div>  <input class="form-control py-2 border-right-0 border" type="search" value="search">  <span><pre class="brush:php;toolbar:false"><div><p><br></p></div><br>

Grid System (Row & Column)

This technique uses the grid system (row & column) to create a search input with an icon. No-gutters are used to eliminate spacing between columns, resulting in a seamless layout.

<br><div>  <div class="col">
<pre class="brush:php;toolbar:false"><input>

<button></button>

Input Group with Prepend

Similar to the input group with append, this technique utilizes an input group with input-group-prepend. The icon is placed in the prepend, located before the input field.


  

    
<button></button>




The choice of technique depends on the desired appearance and functionality. These examples demonstrate several methods for integrating an icon into a search input using Bootstrap 4, providing flexibility in design and implementation.
