Filter categories in dropdown
How Do I?
3 years ago
On a Website i use two category groups: Wine (White, Red, Rose etc) and Food (Burgers, Fish, Seafood etc)
First page has a dropdown with categories of Wine
<form>
<select>
<option value="">Wine</option>
{exp:channel:categories channel="product" category_group="1" show_empty="no" style="linear"}
<option value="{path='pages/vintyp'}">{category_name}</option>
{/exp:channel:categories}
</select>
</form>Linking to second page with categories of Food
<form>
<select>
<option value="">Food</option>
{exp:channel:categories channel="product" category_group="2" show_empty="no" style="linear"}
<option value="{path='pages/vintyp'}">{category_name}</option>
{/exp:channel:categories}
</select>
</form>
{exp:channel:entries channel="product" orderby="post_date" sort="desc"}
{/exp:channel:entries}This will show all the used categories from the category group, but how do i filter out to only show those that correspond the selection of the previous category group?
If select “White” on the first page only “Seafood and Fish” should be in the dropdown on the second page If i select “Red” on the first page only “Burgers” should be in the dropdown.
Any help would be appreciated.

I solved this using exp:channel:category_heading to get current category and exp:query to get the subcategories.
