How to load data into a dropbox

I need to fill the dropbox options with data from a table.
I read data from the table using a Read Data block, read_pai. The model name is dtpai. Retrieve org_id and org_name.

But what should I put in the checkbox options to use this data?

The form loaded the data, but does not show it in the dropbox.

​

I tried:

{var:read_pai.dtpai.org_id}={var:read_pai.dtpai.org_nome}
{var:read_pai.dtpai}
{var:read_pai}

​

Thanks all.

Did you set return type to "an array of key/value pairs" ?

Oohh. No, I didn't.

Thanks, now is working fine.

​

Once more, thanks

Hi, it's me again.

​

One more thing.

​

I have a list of departments, to fill with the senior departament.

Like this:

1= Departament XX

2= Departament VVV

3= Departament ZZZ

]

But I need to insert a line to define the TOPs departments. Like this:

0=Top department

​

How I can do that?

Exactly like that

Simple.

Yes, just like that.

Thanks again.
