Struggling with a drop down list

How to?
#1

Hi,
I am trying to scrape a list from a website where the information is separated by states.
To reveal the list per state you first have to select a state from the drop down list and click the "go" button which than reloads the page with the information for the selected state.

Url: https://americassbdc.org/find-your-sbdc/
Source code: view-source:https://americassbdc.org/find-your-sbdc/

I have been able to make a selctor that finds the name of each state by using an Element that has the selector "option" and the attribute name "value"
How can I make the scraper go through that list of states to than extract the information that is on each of the reloaded pages? The page stays the same, it just reloads the content per state.

I am currently unable to connect the first list with the action of extracting the data I want from each state.
I am looking forward to your pointers on how I can achieve that.. thank you very much for your input.

The state is selected via java script like this:

<input type="submit" id="zipSearch-go" class="btn-search" value="Go">
> 			<script type="text/javascript">document.getElementById('stateform').state.value = 'AL';</script>
> 			</form>
