title: Firebase Query, where condition with select menu.what is the value i need to get all data from the database?
body: <p>i have multiple select menus with default stats &quot;everything in the field&quot;.
  like select city where default option all cities and option2 would be London for example and so on.

  <pre><code>q.value= query(
              collection(db, &quot;Bids&quot;),
              where('City', '==' ,var1),

              where('Status','==',var3)
              
            );
            const querySnapshot = await getDocs(q.value);
