I'm using Liferay Developer Studio 3.8 and Liferay Portal Tomcat 7.3.1.
I was wondering how can I insert Font-Awesome icons in a portlet (portlet4SpringMVC with JSPX in a widget's page) generated through IDE neither theme generator nor Blade CLI.
When I insert Font-Awesome 4 icons, the icon does not show up.
When I insert Font-Awesome 3 icons, the icon shows up replicated:
I already activated Font-Awesome option in System Settings, as stated in this link
This is the code that's being used to test Font-Awesome icons:
<div class="input-group col-md-4">
<input class="form-control py-2" type="search" value="search" id="example-search-input"></input>
<span class="input-group-append">
<button class="btn btn-outline-secondary" type="button">
<i class="icon-search"></i>
</button>
</span>
</div>
