First make sure Font Awesome is installed.
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">
Or use a plugin such as Font Awesome Icons to have it installed for you.
We are going to use the following two Font Awesome Arrows:
<i class="fa fa-arrow-circle-down"></i>
<i class="fa fa-arrow-circle-up"></i>
Next we want to create a new class for these arrows. We are going to use the name awesomearrows. The class definitions need look like so:
.collapseomatic.awesomearrows {
background-image: none;
}
.collapseomatic.awesomearrows:before {
font-family: FontAwesome;
content: "\f0ab";
}
.colomat-close.awesomearrows {
background-image: none;
}
.colomat-close.awesomearrows:before {
font-family: FontAwesome;
content: "\f0aa";
}
Now we need to assign the trigclass attribute our value of ‘awesomearrows’
[expand title="Trigger Text" trigclass="awesomearrows"]Target Content[/expand]
