Can't remove "+" and "-" in "Styles"

Using Accordeon menu with Hikashop patch, configured for Image Only in Mootools
the "+" and "-" images are displayed no matter what I do.

Under the Styles tab I have:
Use images +/- set to "No"

I also tried clearing the path for the values adjacent to:
"Image for +" and "Image for -"

But when I save the configuration, the paths are restored to
modules/mod_accordeonck/assets/plus.png
modules/mod_accordeonck/assets/minus.png

What am I missing - I want the images NOT to be displayed in the menu?

Hi
Please give me your url, and tell me which version of joomla and the module you are using
CEd

I have seen your website, in fact if you choose to open the submenu on image only, you need an image. else how would you open the submenu ?
the option to not display the +/- images is only applicable is you choose to open on the link and image

Hi,

A workaround with css :
in the template.css off your template, add this:

You may need add some <#id> or <.class> information before .open and .toggler if you use those classes somewere else than in your menu.

Hello,

Can't we just change the image plus.png and minus.png with a transparent.gif ?
What is best : changing the image or modify the template.css ?

Thanks
