Hello, I'm working on a dropdown menu that has items from the database using PHP for each loop The code is making only one dropdown item but the database have more than 1 rows so where is the problem?

Table :-
-------------------------------------
| id | Address | text |
-------------------------------------
| 1 | foo | 5 |
-------------------------------------
| 2 | bar | 13 |
-------------------------------------
| 3 | baz | 1 |
-------------------------------------
| 4 | qux | 1 |
-------------------------------------

the dropdown contains [ foo ] only.

What I have tried:

PHP
    <?php foreach($items as $newitem){?>
        <div class="dropdown-menu"  style="height:29vh; width:30vh;"aria-labelledby="myInput">
        <a class="dropdown-item" href="#"><?=$newitem['name'];?></a>
    </div>
<?}?>

You create a new dropdown-menu for each item in the list, instead of adding each item to one menu.

You didn't provide much code for us to see what is going on.

Time to learn how to debug your code.Just by looking the resulting page in browser, you see that something is wrong, by you have no idea what.

First you need to locate where things go wrong:
- Look at source of the page and check what html code was generated and compare with what code you expected.
- Check what is in $items by printing it in the html code, just to see if the array contain what it should.

You should have find enough thing to understand what is going and apply corrections.

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.
