How to create a drop-downlist from previous entered values ?

[smalldragoon]

HI ,
For my need, I require to create with Fabrik elements which are named "fields"
I have then a form which allow me to create these "fields" with : field_name and field_value.
Now, to give a little bit of context, the final purpose is to create a rules / policy with different items.
to do so, I create then , through another form , the "operators" ( same with name & value )
I would like now to create a rule, so I create a new form, with 3 fields expected : Src, operator , value.
I would need then a field which will list in a dropdown list the name of my "fields" available.
it is not cascadejoin as there is no trigger, and can not find a way to use the standard "dropdown" to select values from a table instead of using the list you must manually enter.
Is there a workaround?
Thanks

Did you miss the normal databasejoin element?

let me recheck, I did not managed to generate a drop down list
I checked but worth redoing it a second time then ... ;-)

mm.. my bad ... as operators, I put some values with "<" which always prevented the updates to be saved properly ( there was indeed a message error that I did not read )
Works like a charm...
Sorry for this very basic question then
