Remove default category

I've searched the forums and read the documentation and I'm sure that there must be a simple answer for this (and perhaps a configuration setting hidden in plain sight) but I cannot seem to find how to disable the default product category in the vendor product form.

Thanks Jerome, that works great.

However, is it possible that if no category is selected that the user is prompted to add one instead of automatically assigning one?

My reasoning is as follows (perhaps a little cynical but probably fairly accurate)

- Pre-selecting a category - 90% of users will simply assume that this is normal and so they will not delete it.
- Automatically adding a category - users who forget to select a category will be unaware.

In either case I would bet that for every 100 products added I end up with 95 in the root category.

Much better to have no category automatically selected, and some basic form validation.

Is this easily achievable?

Thanks Jerome.

i ended up adding some simple javascript validation.

in productmarket / form.php I added a javascript function to detect the presence of submitted categories and added an onsubmit call to the form declaration

<script type="text/javascript">
 function validateForm(){
  if (document.forms["hikamarket_form"]["data[product][categories][]"] === undefined){
      alert("Please Select one or more categories");
      exit;
  } else {
      return;
  }
}
</script>

<form action="<?php hikamarket::completeLink('product');?>" method="post" name="hikamarket_form" id="hikamarket_products_form" enctype="multipart/form-data" onsubmit="return validateForm()">

tnx for this and i think its good be if add that as option in market config
