using GWCode Categories, trying to exclude a category group and only show cats assigned to entry_id

Question

I'm using the tag below to display the categories of an entry using the entry_id. I'm using those categories to generate a form. I want to exclude specific category groups as they aren't needed in the form. When I use the tag below, the excl_group_id parameter doesn't work if the entry_id parameter is included. if I remove the entry_id parameter, the excl_group_id parameter works, but it then lists all categories for that channel and not just the selected categories from that entry...Is it possible to get that excl_group_id to work along with the entry_id parameter?

{exp:channel:entries channel="products_beds" disable="categories|member_data|category_fields|pagination" url_title="{segment_4}" sort="asc" dynamic="yes"}

{exp:gwcode_categories entry_id="{entry_id}" channel="products_beds" style="linear" excl_group_id="4"}
    {!— code to generate form based on categories —}
{/exp:gwcode_categories}

{/exp:channel:entries}

Answer 1

I'm not sure why it wouldn't work but rather then delve into the GW code I'd simply use a conditional to remove the categories that aren't required. Should allow you to move on at least :)

{exp:channel:entries
  channel="products_beds"
  disable="categories|member_data|category_fields|pagination"
  url_title="{segment_4}"
  sort="asc" dynamic="yes"
}
    {exp:gwcode_categories entry_id="{entry_id}" style="linear"} //Should work without channel= tag
        {exp:switchee variable="{cat_id}" parse="inward"}
          {case value="4"}
            //Do nothing
          {/case}
          {case default="yes"}
            //Do something
          {/case}
        {/exp:switchee}
    {/exp:gwcode_categories}
{/exp:channel:entries}
