Primefaces DataTable selectCheckboxMenu filter formatting issue

Question

I copied the Primeface showcase for filters located here to my Local JBoss install: http://www.primefaces.org/showcase/ui/data/datatable/filter.xhtml But my selectCheckboxMenu for colors ends up looking like this

I'm using Primefaces 5.0. How can I get it to look like the demo on PF Showcase site?

EDIT

Changed to PF 5.1.RC1 but still no luck

Also tried increasing the width used by the demo for the p:selectCheckboxMenu but with this result

Answer 1

The problem was having the following entry in my custom CSS file which conflicted with the Primefaces.css

label {
    float: left;
    text-align: left;
    margin-right: 0.5em;
    display: block
}
