checkbox not showing

Hi!

First of all want to say, I am enjoying a lot this plugin!

But,

I am at the point where I want to make a mix filter with select types and a checkbox. I’ve been readding and repeatting, refreshing the process changing the shortcode. And it just doesn’t show the checkbox.

What am I doing wrong?

Here the code. Thank you!

<?php echo do_shortcode( ‘[searchandfilter fields=”paises,Deportes,niveles,generos,Edades, precios” types=”select, select, select, select, select, checkbox” post_types=”myposttype” class=”buscador” all_items_labels=”Todos los países” submit_label=”Buscar”]’ );
