Placeholder in eval for populating dropdowns

[bonghetti]

Is it possible to use the placeholder in the populate eval of the dropdown? I need to use it and not cascadingdropdown for multi select. I set up the query but the '{my-> id} doesn't work either. Thank you in advance

... the '{my-> id} doesn't work either.

It's

'{$my->id}'

to be correct.

Element placeholders are not working but "static" placeholders are.
It's '{$my->id}'.
If you need a dropdown changing depending on the change of other elements use a dbjoin element with Data-where with element placeholders + ajax update enabled.

Thanks I solved with static placeholder, but how can I use dbjoin with multiselect?

Set "Render as" multiselect (or checkbox).
