A dropdown dependent on another

Post by zupidupi » Thu Jan 27, 2022 6:37 pm

Hi.

This is probably a pretty standard question.

I have two dropdowns in my component. When the user selects a value in dropdown #1 the choices in dropdown #2 should be updated. The values are stored and properly linked in two tables in my database, so retrieving them is easy.

Any good pointers/examples to how this could be achieved in Joomla?

wonders

Well, I managed to figure it out all by myself! Some fiddling around with the 'showon'-attribute as described here

https://docs.joomla.org/List_form_field_type

solved the matter nicely. I built the xml-code dynamically...works well enough.
