Hi,

I just want to request if possible in next HikaShop Version to have some button that disables Filter to show empty fields.

I had to create a Field in each Personalized Field like "Choose Value" but it's empty, just the Title, this field is to use when a product don't have one characteristic even all the rest had, so if I don't have this field I had to choose some other that is wrong for visitors to see.

The problem is that this field is shown in the filters and everytime I update the hikashop component I have to go to administrator/components/com_hikashop/classes/filters and add this

if(empty($val[0])) continue;
$html.='<span class="hikashop_filter_checkbox">'.$input.'<label for="field_'.$filter->filter_id.'_'.$key.'_'.$divName.'">'.JText::_(JText::_($val[1])).'</label>'.$deleteButton.'</span>';

Hi nicolas,

I think the Overwrite will be something like I'm doing because when I need to update I will always need to check the overwrites for different things in the code.

If you put a button in Configuration > Functions > Filters (don't know if it's the write spelling, mine is in a different language)
Just saying, disable empty values from filters so people like me can turn it on if needed. by default it could be showing everything.

Thanks again
