I have a webform (webform 1) to record data. In another webform (webform 2) I would like to use the submitted data from webform 1 in select options (Load a pre-built option list). How can I do this? Is there any module that already available to do this?
You could try the sandbox project Webform Views Select.
The Webform Autocomplete can do something similar to your requirement: it can allow users to autocomplete answers that were already given for that field on the webform. So if one user types "Manhattan" into a field and submits the form, the next person who uses that webform can start typing "ma", and "Manhattan" (and all other previous answers starting with "ma") will be selectable.
