How do you dynamically setup a select from array

Hi all,
Really simple question:

I have

  1. an array ‘array_type’ which is populated by a page flow.
    image

  2. A select that references the datasource ‘arr_type’
    image

Question:

  1. can I populate the select using an array this way?
  2. If this is possible how do I create/access text and value fields using this method.

Thanks

No worries I have created a javascript function using .add(option),
Would be nice to know tho’ whether selects can be populated from arrays

yes you can by using .split() then $value.
