website functionality

I would like to be able to click on button on one of page of my site, when the button is clicked I would like it to redirect to a dropdown menu with a dropdown menu item already preselected. So, for example if i’m on the homepage, and there’s a button that says click to view the clinical menu, it should redirect to the dropdown on another page with a dropdown, the dropdown should have a clinical option in its dropdown preselected. Please let me know if you have any questions.

Page A has the button, the button is already connected to Page B. Right now its only connected to the page. So, I want it to connect to the dropdown on Page B’s dropdown, specifically the first option in the dropdown, and results should also appear as the button is fired from Page A.

  1. Button (called clinical) on Page A is clicked
  2. We are redirected to Page B where there is a dropdown connect to a database of data
  3. Dropdown on Page B will have the first option preselected in the dropdown, the option is called Clinical, the first option in the dropdown will list its results based on the clicking of the button from Page A

-I’m not very familiar with code, if anyone could please assist me with applying this functionality to my site. Thanks!
