Show a list of subcategories for current category

Question

I'm trying to develop a simple product catalog using categories; I use Transcribe plugin, also.

I've got main categories CAT1 (id4), CAT2 (id5), CAT3 (id6), CAT4 (id7) and subcategories of CAT1: SUBCAT1, SUBCAT2, SUBCAT3. Every main category have its own template page, for example when the user select CAT1 go to page: http://develop/products/group/C4/ On that page I need to show a list of CAT1 subcategories: SUBCAT1, SUBCAT2 and SUBCAT3. I wanna do it dynamically. Now, I can show my subcategories list right set parent_id manually...

{exp:channel:categories channel="products" style="linear"}
    {if parent_id=="4"}
        {exp:transcribe:replace name="category_{category_url_title}"}<br />
    {/if}
{/exp:channel:categories}

I'm able to get the current main category ID...

{exp:channel:entries channel="products" limit="1"}
    {categories}
        {category_id}
    {/categories}
{/exp:channel:entries}

I wonder if there's a way to combine these informations and, simply, get "SUBCAT1, SUBCAT2, SUBCAT3" as output without use any plugins, when I'm on the CAT1 page.

Answer 1

Use Gw Code Categories like as below:

{exp:gwcode_categories cat_id="{segment_3}"}
    {cat_name}
{/exp:gwcode_categories}

OR if you want to use category url title then:

{exp:gwcode_categories cat_url_title="{segment_3}"}
    {cat_name}
{/exp:gwcode_categories}

Output:

-> CAT1
   -> SUBCAT1
   -> SUBCAT2
   -> SUBCAT3

If you don't want to show the "CAT1" category, you can add the incl_self parameter like so: incl_self="no".
