Since the question came up some times allready:
Q: I want the slider without widget title - how to do that?
Answer:
create a new template (main style or all styles you have your slider running)
Name: vbcms_php_no_title
code:
Code:
<div class="cms_widget">
<div class="block">
<div class="cms_widget_content widget_content">
{vb:raw output}
</div>
</div>
</div>
save it.
go to widget configuration of the slider widget, change template name to
vbcms_php_no_title
save. Reload slider. Title is gone.
