Hi all, I'm building a form with two fields of "Value Relation Widgets", one depending on the other.
This works really well as explained here https://youtu.be/ipezh4KXrgo by Alessandro, but I would like that both fields have the multiple selections option. Here is a sample project: https://cld.pt/dl/download/db1a1787-0adc-4633-a0c9-356c41f269eb/drilldown_multiple.zip In that project, I have two shapefiles (one configured without and another configured with 'Allow multiple selections') and two csv files (Value Relation sources). So, without multiple selections option, I simply use "di" = current_value( 'DISTRITOS') as filter expression. This does not work with multiple selections, because this option saves the multiple values between braces: {Value1,Value2,...}. So, how could I use the filter here, to have the second field filtered by the options selected in the first field? Thank you very much! Best regards, Pedro Venâncio
