TOPIC:

Hello, is there a way to create a dependent groupselect?
For example, if I have a table of products (food and tools) from which I want to select using two groupselect - "category" (food, tools) and "subcategory" (fruit, vegetables, meat, hardware, software).
In the first groupselect (category), for example, I choose "food" and based on that, in the second groupselect (subcategory) I am offered only "fruits", "vegetables", "meat" (not hardware and software) to choose from?
Thank in advance for reply.

It is possible. Groupselect automatically reduces the result of other to the Gropupselects.

Nice is exactly what I mean. Can you please direct me to how you created "more search options" on tamiyabase.com.
I'm just a beginner, if you could send me the code, I would be very happy.

Sorry but look here:

joodb.feenders.de/support/documentation.html

I was looking. I created groupselect according to the pattern, but the selection options do not automatically refresh me :(

There is a third Parameter (Boolean / use search)

{joodb groupselect|food|5|1}
or
{joodb groupselect|articles|5|true}

FIELDNAME - Name of a field in your database
rows (optional, integer) - Number of rows for a multiselect form element.
use search (optional, boolean, default no) - Apply the current search to the result.
