title: Use arrow keys (Up/Down) to move through Combobox Dropdown list
body: <p>I created a combobox for the user to type the right name of an item that he's looking for.</p>
  
  <p>The combobox will suggest the possible values that the user can select.</p>
  
  <p>I did this combobox by using <a href="https://trumpexcel.com/excel-drop-down-list-with-search-suggestions/" rel="nofollow noreferrer">this guide</a>.</p>
  
  <p>I found is the only way to select the value is by typing every letter or to click using the mouse in the dropdown list, but I want to allow the user to use the arrows keys to move through the list.</p>
  
  <p>When using that combobox if the user uses the arrow key it selects the first value in the dropdown list therefore removing all other matches.</p>

  <p>I want when using the arrow keys it won't select the value but scroll through the list until he finds what he needs.</p>
  
  <p>I found some people had the same issue but none of them could help me.</p>
