Form select (drop down) component documentation?

UI Builder

Hi I’m struggling to find any information on how to populate a select (drop_down) component with column data from a backendless table.

I’m trying to create 3 cascading drop downs starting with selecting a State … and then having the next Cities drop_down only show that State’s Cities… And once a city is selected then only the appropriate zipcodes show up in the 3rd zipcode drop_down.

If someone could point me in the right direction that would be great! Thanks… BTW I think this might be a good video instruction to do for your youtube channel.

Hello @William_Lee

For this purpose you can use Set Options to Select block

Options argument must be a list of objects with label / value properties.

What about your case:

  • Set options on Page enter(for example) for 1st select
  • On change value of 1st select, set options to 2nd select
    And so on.
